Brass check valve

(0 Customer reviews)

The main purpose of a check valve in a system is to prevent backflow, which could damage equipment or contaminate media upstream. Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a
one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to
protect the piping, other valves, pumps etc.

There are basically two type of check valve:

Vertical check valve (Non return valve)
Horizontal check valve (T type)

Hydraulic Direction Control Valve

( Customer review)

Directional control valves (DCVs) are one of the most fundamental parts of hydraulic and pneumatic systems. DCVs allow fluid flow (hydraulic oil, water or air) into different paths from one or more sources. DCVs will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. A directional control valve is extended and retracts control for your hydraulic cylinders. It provides a flow path from the pump to the cylinders and a return path from the cylinders to the fluid reservoir.Type of direction control valve we are dealing in:

Solenoid Operated Directional Valve
Solenoid Controlled Pilot Operated Directional Valve
Pilot Operated Directional Valve
Poppet Type Directional Valve

Hydraulic High Pressure Ball Valve

( Customer review)

Hydraulic ball valves are usually a kind of special stainless steel ball valves or carbon steel ball valves which are used in hydraulic industry, to control the fluid in the hydraulic systems. Hydraulic ball valves are characterized by below features:

Low fluid resistance, the full bore ball valve basically has no flow resistance.
High pressure: the maximum working pressure can be up to 7500 psi (500 bar), depends on the sizes and connection type, because of this, hydraulic ball valves are also known as high pressure ball valves.
Block body: different from the other types of ball valves such as 1 piece ball valves, 2 piece ball valves, three piece ball valves, fully weld ball valves and so on; the hydraulic ball valves body are in Square shape (Cuboids or cube). See in below picture.
Leak-free and reliable. It has two sealing surfaces, and currently the ball valve sealing surface materials are mostly in a wide range of plastics, good sealing, can achieve a complete seal. It has also been widely used in vacuum systems.
Hydraulic ball valves are with simple structure, small size, and light in weight.
Easy to operate, fast to open and close, from full open to fully closed the rotation only is 90 degrees, so it is easy for remote controlling.
Easy maintenance, ball valve structure is simple, the seal ring is generally active, and removal and replacement are more convenient.
When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
Since the ball valve has wiping during opening and closing, it can be used in media with suspended solid particles.
The end types of hydraulic ball valves to connect the hydraulic tubing usually are female BSP, NPT or UN/UNF thread, male ORFS connection or 24° cone connection.

Hydraulic Non Return Valve

( Customer review)

Check valve is one flow direction valve, which ensures flow in one direction and prevents backflow. It is also known as a non-return valve and it can be used in a vertical or horizontal pipeline. The material used in the high-pressure check valve is commonly Carbon steel or stainless steel and it depends on the workability and needs in an industrial setting.It is also available in different sizes such as DN8 to DN50, usually referred to as 1/4” to 2”. The standard working pressure of the high-pressure check valve is 420 bars for size 1/4” to 1”, while pressure reduces to 315 bars from size 1 1/4” to 2” when valve sizes get bigger.
