GOST CHECK VALVE
Check valve is indispensable in the hydraulic equipment. The check valve is mainly used to control the flow of two-way oil flow and water flow, which has obtained a good reputation for reliability, long service life and low cost.
Product introduction:
A check valve is an energy storage valve with a gate, usually guided by a pressure difference. The gate of the check valve swings according to the direction of pressure difference. The check valve has been widely used in engineering, especially in various hydraulic equipment, such as the pump set of oil field drilling tools, which can be used to control the flow of two-way oil flow, or the pump station of sewage treatment system to control the discharge and recovery of water. The gost check valve is used to prevent water from flowing back from the outlet of the main pipe to the main pipe. The check valve is most commonly used in the inlet pipe or outlet pipe of the toilet tank. When the toilet is filled with water, since there is no blockage, the water can flow freely through the water injection pipe and out of the water outlet. However, once the water level in the tank reaches a certain height, the release arm will lift and the water will flow out of the tank.
Product features:
1. function
The check valve is mainly used for regulation and control. It consists of two flanges, two ball valves and two valve seats. It can be used to adjust the liquid flow at the pipe joint and slide in the guide tube with two openings and valve seats on both sides through the ball assembly.
2.gost check valve is a high-quality watertight ball valve designed to provide accuracy when you inject or pump volatile liquids. It is equipped with a stainless steel ball and a rubber O-ring to provide a tight seal that will not be corroded. The wall thickness of the valve body is 1/8 inch, which makes the check valve very durable in many environments. There are several types of diaphragm, vane and plug valves. These valves are widely used in liquid substances and steam in petroleum, chemical and natural gas engineering.
3. this check valve is easy to install. The outlet inner diameter is 7/8 inch and is suitable for 1-1/2 inch external pipe thread. It can be used to stop water flow or remove condensate from air ducts or overheated air conditioning coils, and other applications that require a check valve to prevent the backflow of liquid, gas, or steam through closed valves.
4. Gost check valve has two specifications: 150 mm and 250 mm. Gost 50mm is used for all types of fire extinguisher check valves, construction machinery, equipment and industrial boilers. It can also be used for sprinkler system water supply, clean water circulation, boiler water supply system, etc.
5. our two in one PVC ball valve is an important accessory in your family and garden. As long as you want to move the liquid on the lawn or pool, you can use it to control the flow of water, air or other liquids. It is light, durable and easy to install, so now you can apply fertilizer without pulling out the water pipe and sprinkler!

Application & Function:
APIRT Cast steel swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position.
APIRT Cast steel Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
Accessories:
Accessories such as bypasses, locking devices, counter weight and many others are available to meet the customers’ requirements.
