We are proud to be the Australian Distributors of Cla-val Control Valves, including the Cla-Val Models 50-01 and 650-01 Pressure Relief Valves. These modulating valves are designed to maintain constant upstream pressure within close limits and are perfect for pressure relief, pressure sustaining, back pressure, or unloading functions in a by-pass system.

The Model 50-01 is the full port version, while the Model 650-01 is the reduced port version of the valve. These valves are ideal for pressure sustaining service, preventing "robbing" of the upper zone, and providing system protection against high-pressure surges in pressure relief service.

Their fast opening and slow-closing feature dissipates excess pressure to a safe location, ensuring smooth control and positive pressure regulation.
