S Type of Check Hydraulic Pressure Regulator Check Directional Valve
The function of S type check valve is making the oil flow in one direction, but stop in another direction Connection type: pipe connection.
The working principle of an S-type check valve (also known as a non-return valve or one-way check valve) is based on the unidirectional control of fluid flow. Its primary function is to allow fluid (liquid or gas) to flow freely in one direction while preventing backflow in the opposite direction.
S-type check valves typically feature a specific flow path design, ensuring reliable operation even under low pressure or low flow conditions.Their compact structure makes them suitable for installations with limited space.
