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;

3. Sequence valve and balance valve. Depending on the pressure of the gas circuit, some control is performed.

Next, we mainly introduce you this single-seat cut-off pressure control valve.

Single Seat Globe Pressure Control Valve advantages:
Hydraulic pressure control valve has Long life

1. Single Seat Globe Control Valve Valve Trims

According to the needs of the working conditions, different materials and surface hardening treatment can easily be chosen to meet the requirements of each function module of trim to improve its performance of the corrosion, cavitation and erosion resistant, lengthen service life.

2. Pressure Control Valve body

The body of LN8 Single Seat Globe Valves consists of two passages from upper and lower, forming a shape like letter "S". The design of an elliptical section reduces the flow resistance and turbulent flow to keep the flow fluent. The flap in the middle of upper passage can reduce the eddy flow and increase the flow capacity.

3. Single Seat Globe Valve Actuator

The standard mate of Single Seat Globe Valves is AM8 Multi-spring pneumatic diaphragm actuator, which can be used in many conditions with the features of strong output force, high reliability, long lifespan and extensive applications. The output force changes with the number of springs. The high stress resistant diaphragm, bearing maximum pressure of 0.5 MPa air supply, gives globe valves a reliable shutoff. This type of actuator has a long life cycle with more than 1

Feature:
Suitable for clear fluid lines such as Water, Liquid, Gas, Steam, etc.
This valve is used in systems that require precise flow control and where leakage and air-tightness are critical.

Application:
It is essential for the flow line of each industry. Mainly used in plant automation facilities due to excellent precision control such as flow rate, pressure, temperature, etc.

Characteristics:
1. For excellent wear and tear resistance, Stellite welding is used by default on core
components such as plug and seat ring.
2. It is possible to achieve excellent durability of the unfavorable fluid condition and high
temperature through heat-treatment on parts of the stem and trim
3. The selection of accurate trim and material through extensive testing and rich
experience in technical solution
4. In case of a product related problem, we have technical personnel who can
immediately assess the situation and resolve the issue

ultra small flow needle valve is a kind of top guide single seat valve, it has a simple structure, good sealing performance, reliable use and so on. The top guide system is effective enough to overcome the small opening shock, effective and long service life. A smaller flow coefficient is chosen to increase the use of the valve. Multi spring pneumatic film mechanism or electric actuator can be selected.
The valve is the use of , professional development of a small flow of the operating conditions of a product. The body is small in size and light in weight, and the inner screw thread structure is more convenient to be installed and disassembled. The whole body has the characteristics of small size, light weight, high performance and precise control of micro flow.Does not apply to the medium of the more dirty occasions, adjusting the media containing granular media, should be aimed at the problem of small throttle clearance, pay attention to prevent the occurrence of blocking card phenomenon. Especially suitable for liquid, steam and other media in the mainstream of the regulation.

ZJHS pneumatic piston control valve consists of a ZSA (B) spring piston actuator and a compact single seat (sleeve) valve body. The structure is lighter and smaller, and the thrust is larger, but the sensitivity is slightly worse. pneumatic piston control valve is equipped with an electric-gas valve positioning or pneumatic valve positioner to achieve automatic adjustment and control of the fluid medium in the process pipeline. It is widely used in precise control of gas, liquid, steam and other media process parameters such as pressure, flow, temperature, liquid level and other parameters to maintain a given value. The spool of pneumatic piston control valve adopts balanced structure, large allowable pressure difference, good vibration resistance, low noise, good stability, easy assembly and disassembly, and different pressure ranges can be selected to obtain the required differential pressure.pneumatic piston control valve is used in industrial operation process automatic control systems that require low noise, large working pressure difference or limited installation position and fast response speed.

ZJHL pneumatic cage control valve is a top-guided low noise control valve consisting of a multi-spring pneumatic actuator and a low flow resistance cage regulator valve body. The multi-spring actuator is low in height, light in weight and easy to install. The valve trim uses a single-seat piloted spool. Pneumatic diaphragm cage control valve mainly uses the pressure of the fluid to achieve rapid movement of the spool and low operating force.
