Denison Check Valves

Denison Hydraulics C4V and C5V series direct/pilot operated check valves…

Denison C4V series direct/pilot operated check valves allow free flow from A to B. The counter direction is blocked. Series C4V valves are equipped with a leak-free seat type cartridge.

Denison C4V check valveThe pressure arising in port A lifts the poppet from the valve seat and releases the flow to B. In the counter direction, the spring and the pressure on top of the cartridge hold the poppet onto the seat and block the flow.

Features include: high flow, low pressure drop design and minimal internal leakage.

The Denison C4V check valve series is available in a number of nominal sizes: C4V03, C4V06 and C4V10.

Denison C5V series direct operated check valves provide free flow in one direction and block the flow in the counter direction.

Denison C5VThe SAE flanges allow the C5V to be mounted directly on the pressure port of pumps for protection against pressure shocks from the system.

The ball is held on its seat by a spring under zero pressure condition. When flow is increased to the cracking pressure, free flow is allowed from port A to port B. Blocked flow is created when operating pressure and spring on Port B exceed pressure on port A.

Features of the Denison C5V check valves include: direct operated check valve, SAE 61 and SAE 62 flanges, 4 sizes (SAE 3/4″, 1″, 1 1/4″, 1 1/2″), 3 springs and 2 different seal configurations.

The Denison C5V check valve series is available in a number of nominal sizes: C5V06, C5V08, C5V10 and C5V12.
