What is Check Valve?
What is Non Return Valve?
What is NRV?
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.
Dharmi
Engineers all check valves are self actuating type. Dharmi
Engineers manufacturer & exporter of wide range of
Industrial Check Valve (Non Return Valve).

Dharmi Engineers Swing Check Valves [Non Return Valves] are Swing Type and Bolted cover
design Construction. The one piece disc construction is securely fastened to the hinge by means of a lock nut & pin. The Disc is free to rotating type to avoid any other wear. The hinge pin offers excellent wear resistance properties.
Swing Check valves also can be supplied with Titling disc design, Dash pot arrangement and outside lever & weight design for use where control of the disc is desires.
Swign Check type Non Return Valves can be mounted on Horizontl &
Vertical both line.
Dharmi Engineers also offer P.T.F.E. (PFA / FEP) Lined Ball Type / ”Y” Type & Rubber Lined Flap Type Check Valves for high corrosive application. |
