PPH AIR RELEASE VALVE

PPH AIR RELEASE VALVE MANUFACTURER

PPH Air Release Valve Manufacturer and Suppliers in India. In pressurized pipe systems, an automatic air release valve is essential.

The air locked in the pipe will gradually rise upwards and accumulate at the highest points of the system. Pump breakdown, incorrect instrumentation measurements, malfunctions, flow problems, and water spurts or pressure spikes can all be caused by trapped air. Unwanted air in the tube also makes the pump work harder, which uses more power.

The purpose of a PPH air release valve, also known as an air relief valve, is to relieve trapped air that collects at each maximum height of a full pressurized tube. As the internal lever system increases the temp force to exceed the internal pressure, an air release valve may open against the internal pressure.

When gas bubbles form in the valve, the greater force opens the opening. PPH air release valves are critical to pipeline productivity and protection against water ingress.

The purpose of the VA air release is to eliminate any air entering the pipe with the liquid.

• Connection system for solvent weld and threaded joints
• No metal parts in contact with the fluid
• Can be used as a vacuum breaker valve when installed with the nut at the
bottom
• Valve material compatibility (PVC-U) with water, drinking water and other
food substance conveyance according to current regulations
• Can be maintained with the valve body installed
