The reduced cavitation characteristics of the 100-20 Hytrol Valve are the basis for the Cla-Val 600 Series. The rugged simplicity of design and pack-less construction assures a long life of dependable, trouble-free operation. Its smooth flow passages and fully guided disc and diaphragm assembly assure optimum control when used in piping systems requiring remote control, pressure regulation, solenoid operation, rate of flow control or check valve operation.
