What Is a Check Valve? Check valves are usually installed in the pipeline to prevent backflow. A check valve is basically a one-way valve in which the flow can flow freely in one direction, but if the flow turns, the valve will be closed to protect the piping, other valves, pumps, etc. If the flow is diverted without a check valve installed, a water hammer may occur. Water hammer often occurs with extreme force and can easily damage pipes or components. Check Valve Definition A check valve is a fundamental component in fluid systems, playing a crucial role in regulating the flow of liquids or gases. This simple yet essential device prevents backflow and maintains the desired direction of fluid movement. Understanding the function and types of check valves is essential for engineers, manufacturers, and anyone involved in fluid control systems. How Does a Check Valve Work? Check valves operate on a straightforward principle: allowing fluid to flow in one direction while preventing reverse flow. The valve consists of a movable mechanism, often a disk or a flap, and a body with an inlet and an outlet. When the fluid flows in the intended direction, the mechanism opens, enabling the fluid to pass through. However, when there is a reversal in flow, the mechanism closes, preventing the fluid from going backward.
Soft-sealing gate valve is the replacement of the traditional gate valve, the use of flexible disc produce trace deformation compensation effect, achieve good sealing effect, the valve has the switch light, reliable sealing, elastic memory and long service life etc, can be widely used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems and other fluid on the pipeline as the adjusting and intercepting device is used. Features: Flat-bottomed seat traditional gate valves are usually deposited in the bottom groove of the valve due to external objects such as stone, wood, cement, paper, debris, etc., after flushing the pipe with water. Cause cannot close tightly and form slack phenomenon, soft-sealing gate valve using the same as the pipe at the bottom of the flat design, not easy to cause debris deposition, the fluid flow unimpeded, the whole package glue valve plate is made of high quality rubber, within the whole outsourcing, domestic first-class rubber vulcanization technology make the valve plate after vulcanization can ensure accurate geometry size, and rubber and nodular cast iron gate connecting firm, not easy to fall off and elastic memory preferred. The corrosion resistant valve body is painted with powder and epoxy resin to prevent corrosion and rust of the valve body, and can be used in sewage system. Not easily broken into traditional cast iron...

Hitesh Metal is one of the well-known manufacturer & trader for high quality Steel Ball Valves , which is a split ring that is engineered and designed to give a pre - measured minimum gap for socket welds. This valve is used in combustible gas trains in many industrial applications. Stainless Steel Ball Valves offered by Hitesh Metal are used in hydraulic and pneumatic systems because the needle valve allows for precise flow regulation when there is low flow in a non - hazardous environment. These valves replace existing traditional techniques employed by pipeline engineers to generate a double block and bleed configuration in the pipeline. Carbon Steel Ball Valves is often used for critical process service, which are for high pressure systems or toxic / hazardous fluid processes. Applications that use valves include instrument drain, chemical injection connection, chemical seal isolation, and gauge isolation. Alloy Steel Ball Valves offered by Hitesh Metal do the work of three separate valves (two isolations and one drain) and require less space and have less weight. This design also has operational advantages, there are significantly fewer potential leak paths within the double block and bleed section of the pipeline. Because the Duplex Steel Ball Valves are full bore with an uninterrupted flow orifice they have got a negligible pressure drop across the unit. The pipelines where these valves are installed can also be pigged without any problems. Hitesh Metal also offer these Nickel Alloy Ball Valves in different sizes, shapes and designs as per customers specifications at affordable rates.

All types and all size of Butterfly valve available.
A wide variety of valves are described in this section. All the valves are made of Borosilicate glass body and PTFE plugs so that process fluid comes into the contact of glass and PTFE only. Borosilicate glass body permits the visual checking of the operation. All the valves are suitable for operation under full vacuum conditions and a maximum temperature of 200ºC
Step-by-step direct-acting solenoid valve Principle: It is a combination of direct motion and pilot type. When there is no pressure difference between the inlet and the outlet, after energization, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward, and the valve opens. When the inlet and outlet reach the starting pressure difference, after the energization, the electromagnetic force leads the small valve, the pressure of the lower chamber of the main valve rises, and the pressure of the upper chamber drops, so that the main valve is pushed upward by the pressure difference; when the power is off, the pilot valve uses the spring The force or medium pressure pushes the closure and moves down to close the valve. Features: It can also be operated at zero pressure difference or vacuum or high pressure, but the power is large, and it must be installed horizontally. Pilot solenoid valve Principle: When energized, the electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, and a pressure difference between the lower part and the lower part is formed around the closing member. The fluid pressure pushes the closing member upward to move the valve to open; when the power is off, the spring force leads the pilot. The hole is closed, and the inlet pressure passes through the bypass hole. The rapid chamber forms a lower high and high pressure difference around the valve closing member, and the fluid pressure pushes the closing member downward to close the valve. Features: The upper limit of the fluid pressure range is high, can be installed arbitrarily (customized), but must meet the fluid pressure difference conditions. 2, the difference between the solenoid valve from the valve structure and material and the principle, divided into six sub-categories: direct-moving diaphragm structure, step-by-step direct diaphragm structure, pilot diaphragm structure, direct-acting piston structure, Step-by-step linear motion piston structure and pilot piston structure. 3. Solenoid valves are classified according to their functions: water solenoid valve, steam solenoid valve, refrigeration solenoid valve, low temperature solenoid valve, gas solenoid valve, fire solenoid valve, ammonia solenoid valve, gas solenoid valve, liquid solenoid valve, miniature solenoid valve, Pulse solenoid valve, hydraulic solenoid valve normally open solenoid valve, oil solenoid valve, DC solenoid valve, high pressure solenoid valve, explosion-proof solenoid valve, etc.
