PRESSURE SUSTAINING VALVES

Valsteam pressure sustaining valves - ps45-series

PS45

The ADCA PS45 series pressure sustaining valves are single-seat bellows sealed controllers, operating without auxiliary energy, designed for use on steam, compressed air, and other gases compatible with the construction. They are particularly suitable for sustaining steam pressure in all energy and process systems where upstream pressures must be kept under control.

valsteam pressure sustaining valves - ps4

PS4

The ADCA PS4 series direct-acting, spring-loaded diaphragm sensing, pressure sustaining valves are designed for use on compressed air, water, and other gases or liquids compatible with the materials of the construction. This valve’s main purpose is to maintain the upstream pressure under control. They are suitable for pressure sustaining applications where small loads are involved. They are also specifically recommended to operate as pilot valves in combination with other pressure regulators.
