Advantages Of Resilient Seated Gate Valve BS5163

The resilient seal and sturdy construction make the valve durable and long lasting. It can withstand high pressure and temperature changes.

The resilient O-ring seal provides a reliable bubble-tight shut-off. The seal material can be chosen to suit the application.

The resilient seal requires lower operating torque compared to metal-seated valves, making it easier to operate manually.

The O-ring seal is easily replaceable, allowing the valve to be repaired or maintained without having to replace the whole valve.

The valve material can typically be chosen to suit a wide range of applications and media being handled – water, chemicals, air, steam, etc.

The valve conforms to BS5163, ensuring it meets relevant safety standards for design, materials and testing.
