Swing check valves

Swing check valves are also called or a one-way valve, its role is to prevent the backflow medium pipeline.Open-close part by medium flow and power to open or closed, to prevent the backflow medium valve check valve.Check valve belong to automatic valve class, mainly for the one-way flow of medium pipeline, only allowed to medium flows in one direction, in order to prevent accidents.This valve shall generally be installed in the pipeline.

Swing check valves within the adoption of the rocker arm swing structure, all the opening and closing of the valve is mounted on the body, not through the body, in addition to the flange parts in useSealing gasketandSealing ringOverall no outside funnelled, put an end to the valve leakage.Swing check valve rocker arm and the disc joint adopts spherical connection structure, make the disc worldwide in 360 - degree must haveDegrees of freedomAnd there is propertracePosition compensation.
Apply to clean medium, should not be used for large medium containing solid particles and viscosity.

Bolted Cover Design, Flanged End Swing Check Valve Manufacturer
Suitable For Horizontal & Vertical Line Non Return Valve Manufacturers


These types of valve (Non Return Valves) are used to stop back flow to the upstream side of the valve. The design of Check Valve (Non Return Valve) is very simple. A hinged door is placed inside the Swing Check Valve body. With the pressure coming upstream the door is held open; When pressure increases on the downstream side, it forces the door to valve close, stopping any back flow. Mostly all pump discharge line check valves being used. Swing type check valve is performing in vertical and horizontal both line. Lift check valve have have vertical and horizontal both type of design to suit as per line. Dharmi Engineers Flanged End, 150# & 300# Check Valves are Swing Check type and the 800# class check valves are Piston Type Lift Check Valves. The piston type valve works up and down providing a strong, firm seal under high pressure conditions.
