RFT Direct-Activated Pressure Sustaining Valve
Description
Pressure sustaining valves are designed to maintain a pre-set back pressure, if the back pressure drops to the set value the valve will begin to close to maintain back pressure, when pressure returns the valve will begin to open again.
Typically used to maintain pressure for critical systems upstream, by limiting flow to non-critical systems down stream if required to do so.
Features
• Maintains stable pressure in pipeline systems.
• Suitable for automated control systems and various general fluid applications.
• Suitable for both horizontal and vertical installation.
• Wide capacity range, capable of handling local water supply pressure and adapting to specific pump specifications.
• The adjustment nut allows for easy pressure regulation.
• Constructed with 316 stainless steel for durability and compatibility.
• Easy to maintain, with maintenance parts available upon request.

RFT Direct-Activated Pressure Sustaining Valve
The RFT direct-acting pressure-sustaining valve is installed in user water supply pipelines to coordinate with the minimum operating pressure of the main water supply line, ensuring balanced upstream and downstream water pressure.
