Dual Check Valve

DENZ-C19 Dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve. The Double Plate Check Valve employs two spring-loaded plates hinged on a central hinge pin.

• Due to its light weight and ease of installation, dual

plate check valves can be installed more easily and

require less maintenance.

• There is a spring-torque control mechanism on the valve

that enables it to open smoothly without any friction.

• A long service life makes it easy to preserve and repair

the valve.

• Their application ranges from heating and cooling to

liquid, gas, and steam.

• Besides steam and condensate pipes, check valves

can also be used in water supply, oil, and natural gas

pipelines.

• Horizontal or vertical installation is possible with the

dual check valve valve.

• It is possible to install them at any position with the help

of the appropriate springs.

• To prevent corrosion and rust from occurring, the shaft

of the valve is made of stainless steel material.

• The seat surfaces are self-seating, reducing dragging.

• When flow is determined in the system, expanders shorten and halves discs and allow fluid to flow

between the disc and the body.

• With disc spring force, the disc sits on the EPDM sealing rings on the body when the flow stops.

• Easily installed between two flanges due to its short installation length and eye screw (hook).

• There is no need to perform any maintenance on the valve.

• 100% of the valves are subjected to Hydrostatic tests according to EN 12266-1. Pressure for seat: PN x 1.1 ,

for shell: PN x 1.5
