With a wide variety of special as well as standard materials for bodies and O-rings, CVH Series check valves offer a cost-effective package of high flow capability and long cycle life
Versatility to match exact user system requirements is combined with a cost-effective package of high flow capability and long cycle life on CVH Series check valves, developed jointly by Circor Instrumentation Products Group companies Hoke International and Circle Seal Controls.
With a wide variety of special as well as standard materials for bodies and O-rings, or all-metal construction, these check valves can be used where temperatures range from -196 to +482C and where chemical compatibility is a consideration.
A metal-to-metal seat allows a floating O-ring to cushion and seal the valve without chatter or damage from high pressure.
This enables them to be used in systems with pressures up to 6000 psi and to offer exceptionally high flow capacity up to 11.6 Cv.
The O-ring is washed by the system media, using Circle Seal technology, and the metal seat prevents any deformation or extrusion of the O-ring.
This increases valve life to in excess of 100,000 cycles, reducing maintenance needs and costs.
Imperial and metric sizes are available, from 1/8in to 1in and 4mm to 25mm, in a variety of configurations including NPT, BSP and SAE, and with the additional option of integral Hoke Gyrolok tube fittings.
Inlet and outlet connections can be different to overcome system compatibility problems.
