Pressure Control Valve
Pressure control valves are capable of regulating the system pressure to adjust the force on the hydraulic piston rod or the torque on the hydraulic motor shaft. Pressure relief valves are used to set the maximum pressure in the circuit and prevent it from being overloaded. Pressure reducing valves permanently maintain the output pressure at the set value while preventing overloading of the equipment. Unloading valves are designed for economic pressure control in accumulator operating circuits and are used as a power source for emergency control.
Classification of pressure control valve
In the pneumatic transmission system, all pressure control valves work on the principle of balance between air pressure and spring force, which can be divided into the following three categories:
1. Pressure reducing valve. Also known as pressure regulating valve, setting device (precision pressure reducing valve), etc., it plays the role of pressure reducing and stabilizing;
2. Overflow valve. Also known as safety valve, pressure-limiting shut-off valve, etc., it plays the role of pressure-limiting safety protection;

Rotary Plug Valve
A rotary plug valve with a plug-shaped flow-restricting component that follows an eccentric path as it rotates. The plug does not contact its seat until it is rotated to within a few degrees of the closed position. When the plug contacts or "cams" into the seat, the seat surfaces are dynamically aligned for closure. This rotary plug valve type may also be referred to as a rotary globe valve.
How rotary plug valve work:
When the material in the upper bunker falls under its own weight and fills the space in the rotor blade, it rotates with the blade to the lower outlet and is discharged. Rotary plug valve can continuously supply and discharge materials. The rotary plug valve can play the role of feeding and locking the air flow in the pneumatic conveying system. Due to the low-speed rotation of the rotor and the very small gap between the rotor and the inner cavity of the housing, the reverse flow of the air flow is effectively prevented, thereby ensuring the stability of the air pressure in the system and the normal discharge of materials.

What is Globe Control Valve
A globe control valve is a type of control valve that is designed to regulate or control the flow of fluid through a pipeline. It consists of a movable disk or plug, which is positioned in the flow path and can be moved by an actuator to regulate the flow of fluid. The valve body typically has a spherical shape, hence the name "globe valve."
The globe valve can be used to control the flow rate, pressure, and temperature of a fluid. It is commonly used in applications such as process control, oil and gas refining, power generation, and water treatment. The valve can be operated manually, electrically, or pneumatically, depending on the application requirements.
Globe valves are known for their precise flow control and low-pressure drop, making them an ideal choice for applications that require high accuracy and performance. They can also be used in harsh environments and can withstand high temperatures and pressures.
Industrial Globe Valves
Industrial globe valves are used in all industries where throttling or regulating flow is required. These include oil and gas, petroleum, petrochemical, pulp and paper, marine, power generation, mechanical construction and industrial gases.

Globe Valve Applications
Globe valves are suitable for a wide range of applications, depending on the purpose and the raw materials used. They are reliable in high-temperature and high-pressure service, regulating steam and condensate, and even in nuclear power plants.
They can also be applied in these other disciplines:
Cooling water systems
Fuel oil systems
Boiler vents and drains
Turbine seals and drains
Globe Valves For Flow Control
Globe valves are used to regulate flow in pipelines and consist of a removable disc (also known as a plug) element and a fixed ring seat usually located in a spherical valve body. The inlet and outlet of the globe valve body are separated by an internal baffle. The baffle has an opening that forms a seat into which the removable disc/plug can be screwed to close (or shut off) the valve.
Common Applications
Globe valves are available in a variety of sizes (NPS 1/2 through 36) to provide users with high performance and reliability. They can help solve a variety of application needs from large to small, hot to cold, and general to severe.
Bonnets are available in a variety of styles to accommodate different application temperatures. These primarily include standard bonnets and optional extension bonnets that can be used to protect the packing when the valve is used in extremely hot or cold applications.
Special packing configurations are also available for applications where a packing system is required to keep fugitive emission concentrations below ambient standards.
Oil And Gas Valves
Oil and gas valves are crucial components of any oil and gas production facility, refinery or distribution system.
Here are some of the most common types of oil and gas valves and their features:
1. Ball Valves: Ball valves are commonly used in oil and gas applications due to their high reliability and minimal maintenance requirements. These valves are designed with a rotating ball with a hole that allows or prevents the flow of fluids.
2. Gate Valves: Gate valves are commonly used in the oil and gas industry for on/off control of fluid flow. They are designed with a wedge-shaped gate that slides into the valve body to control the flow.
3. Globe Valves: Globe valves are used for various applications including isolation, throttling, and regulating flow. These valves have a disk that moves perpendicular to the flow of fluid to control the flow rate.
4. Check Valves: Check valves are designed to ensure that fluid flows in only one direction, preventing backflow. These valves are commonly used in pipelines and other critical oil and gas applications.
5. Butterfly Valves: Butterfly valves are designed with a disc that rotates around an axis to control fluid flow. These valves are commonly used in low-pressure applications where space and weight considerations are important.
6.Needle Valves: Needle valves are used for precise flow control of fluids. These valves have a small orifice and a tapered needle-shaped plug that provides accurate flow rate control.
V Notch Ball Valves
Our V-Ball, V-Port and v notch ball valves are made of high-quality materials. v notch ball valve, the "V" notch is a unique design that allows for precise flow and the ability to regulate and control flow through a 30�°, 60�° or 90�° V "notch". The v notch ball control valve is a low-maintenance valve with a tight bubble shut-off function. All v notch ball valves are highly manageable and can operate at high temperatures (up to 1000�°F) and pressures up to 500PSI (liquid) and 150PSI steam. V notch ball valves are cost-effective compared to valves with similar pressure drops and low flow control (down to 0.07) Cv. The v notch ball control valve is cost effective compared to valves with similar pressure drop and low flow control (down to 0.07). Our v notch ball valves can be manually configured or actuated for automated handling and control. These valves are available in ANSI flange, NTP (threaded) and socket weld.
V Notch Ball Valves introduction:
VN6 series V-notch ball valve, is concentric segmental ball valve for modulating applications. Its V-notch segmented ball permits wide range ability and produces an equal percentage flow characteristic. As the V-notch ball rotates into the seat ring, it creates a wedging and shearing effect to prevent dragging or slurries between the seat and the ball.Our v-notch ball valves normal size is 1" to 12".
V Notch Ball Valves Advantage:
The v-notch ball valves are used settled and also clamped driven shaft plus sphere shaft with splined connection made for absolutely no shed motion for very accurate placing and specific control.
Rotary Plug Valve
A rotary plug valve with a plug-shaped flow-restricting component that follows an eccentric path as it rotates. The plug does not contact its seat until it is rotated to within a few degrees of the closed position. When the plug contacts or "cams" into the seat, the seat surfaces are dynamically aligned for closure. This rotary plug valve type may also be referred to as a rotary globe valve.
How rotary plug valve work:
When the material in the upper bunker falls under its own weight and fills the space in the rotor blade, it rotates with the blade to the lower outlet and is discharged. Rotary plug valve can continuously supply and discharge materials. The rotary plug valve can play the role of feeding and locking the air flow in the pneumatic conveying system. Due to the low-speed rotation of the rotor and the very small gap between the rotor and the inner cavity of the housing, the reverse flow of the air flow is effectively prevented, thereby ensuring the stability of the air pressure in the system and the normal discharge of materials. Therefor, rotary plug valve is an important part of the high-pressure gas to the material transportation in the state of the pipe network. The rotary valve is used as the unloader of the silo in the material collection system.
Stainless Steel Globe Valve
Globe valves are commonly used in pipelines to control the flow of viscous fluids such as oil. These globe valves for sale are suitable for both on/off operation and throttling - flow control. In this type of valve, flow control is determined by the difference in distance between the poppet and the seat. It is important to note that globe valves have a higher pressure drop than many other types of valves due to their S-shaped passage.
Features
Both throttling and shut-off function, small valve stroke.
Specialized stainless steel material for the whole series, more corrosion-resistant
Good sealing performance, no wear and tear, no scratches, long service life.
