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.
Forbes Marshall’s pilot operated pressure reducing valve (FMPRV41), is an SG pilot operated pressure reducing valve that is suitable for compressed air or steam.
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)
