Pressure relief and sustaining valve manufacturers in India

Speciality Valves is among most trustable Pressure relief and sustaining valve manufacturers in India that provide world-class and high-precision valve manufacturing, meant to control the pressure of systems safely and effectively. These are necessary components of safety in pipe and pump systems as well as preventing pressure spurs and pressure lows.

Why Required?

In any fluid system, sudden pressure increases or decreases can lead to equipment failure, safety hazards, and inefficiencies in operation. Pressure relief valves avoid over-pressurization, while sustaining valves maintain a minimum pressure level within the system. They collectively ensure reliable performance and safeguarding of your infrastructure.

Key Components of Pressure Relief and Sustaining Valve:

Valve body (Ductile Iron, Stainless Steel, Cast Iron)

Pilot control system

Spring mechanism

Diaphragm or piston actuator

Seat and plug

Adjustable control settings

Working of Pressure Relief and Sustaining Valve:

The sustaining function causes the pressure relief function to engage when system pressure goes above a pre-set threshold, allowing the valve to open and vent excessive pressure in a safe manner. The sustaining function keeps the valve closed until the upstream pressure crosses a desired value, allowing the system to run stably. The dual-function valves provide pressure control and protection of the system.
