COS-R Series are pressure reducing valves. COS Series are pressure reducing valves with a built in separator and free float steam trap. These valves are, ideal for sudden load changes, available in various material and sizes, self aligning, shock absorbing and have an advanced pilot design to maintain secondary outlet pressure with accuracy. All internals contain a stainless steel construction, and 2 1/2″ and larger have a silencer for noise reduction.
The Forbes Marshall Pilot Operated Pressure Reducing Valve, FMPRV41 is an SG iron pilot operated pressure reducing valve suitable for steam or compressed air. The Forbes Marshall Pilot Operated Pressure Reducing Valve, FMPRV53, is a cast steel pilot operated pressure reducing valve suitable for steam or compressed air.
The HD-Series Pilot-Operated Regulators are used on steam applications for pressure reduction or controlling product temperature (when steam is used in heating applications). The Pilot-operated regulators are more accurate and available in higher capacity than Direct-Operated regulators.
The W91/W94 Self-Operating Temperature Regulator is a mechanically operated device designed to regulate system temperature by modulating the flow of a heating or cooling fluid in response to temperature changes; requires no external power source. They are recommended for controlling temperature on relatively stable systems, where small valve stroke modulations will correct temperature drift.
