High Quality Steel Casting stainless steel check valve
Check valves are called reverse flow valves, check valves, back pressure valves, and one-way valves. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve. Stainless steel check valve is divided into lift type stainless steel check valve, swing type stainless steel check valve, disc type stainless steel check valve.

ANSI Check Valve
The function of this lifting check valve is to allow the medium to flow in one direction only, and to stop the flow in the opposite direction. Usually, the valve works automatically. Under the action of fluid pressure flowing in one direction, the valve clack opens. When the fluid flows in the opposite direction, the adjusting tank acts on the adjusting seat by the fluid pressure and the weight of the adjusting flap to cut off the flow.

Lined Diaphragm H44 Check Valve
A lined diaphragm H44 check valve is a type of valve that is commonly used in industrial settings. It is made up of a diaphragm, which is a flexible material that separates the valve body from the flow medium, and a valve seat that controls the flow of fluid with full bore and no flow resistance. The valve is designed to allow fluid to flow in one direction only and prevent backflow.

Petroleum&Petrochemical Fluorine lined Check Valve
The valve is connected by a pair of clamps, and the structure is tight. Because of the short closing stroke and spring yellow loading, the closing speed is fast, which can significantly reduce the water hammer phenomenon. The valve has the characteristics of small volume, light weight, sensitive action, reliable sealing, convenient installation, etc. It can be installed horizontally or vertically.

Petroleum & Petrochemical Check Valve
The function of this swing check valve is to allow the medium to flow in one direction only, and to stop the flow in the opposite direction. Usually, the valve works automatically. Under the action of fluid pressure flowing in one direction, the valve clack opens. When the fluid flows in the opposite direction, the adjusting tank acts on the adjusting seat by the fluid pressure and the weight of the adjusting flap to cut off the flow.

High Quality Steel Casting Power Station Check Valve
The air discharge stop callback is installed on the outlet pipe of the high pressure feed pump of the thermal power unit to prevent the backflow of the feed water and protect the feed pump. This regulation works automatically with the minimum flow of the water pump and the loop bypass.
-
Lined Diaphragm H42 Check Valve
Full bore in vertical installation and less impact force.
-
Lined Diaphragm H41 Check Valve
Full bore in horizontal fixing and less impact force.
-
Lined Diaphragm H74 Check Valve
Light weight, low cost, vertical&horizontal
-
Lined Diaphragm H76 Duel-plate Check Valve
The valve is connected by a pair of clamps, and the structure is tight. Because of the short closing stroke and spring yellow loading, the closing speed is fast, which can significantly reduce the water hammer phenomenon.
-
Nickel Base Alloy High Pressure&Temperature Check Valve
In order to ensure the high requirements for the tightness, reliability and safety of the screen door, the valve body is made of nickel base alloy as a whole, or fabricated and welded.

GB Swing Check Valve
The function of this swing check valve is to allow the medium to flow in one direction only, and to stop the flow in the opposite direction. Usually, the valve works automatically. Under the action of fluid pressure flowing in one direction, the valve clack opens. When the fluid flows in the opposite direction, the adjusting tank acts on the adjusting seat by the fluid pressure and the weight of the adjusting flap to cut off the flow.
