Compact Light-Weight Design
Provides space and weight saving on platforms, reduced shipping and handling costs and minimal structural support.

Threaded Valve Insert
Designed to take full working pressure, which does not rely on the mating flange to hold internals.

Oliver Swivel Flanges
Designed to allow hubs to be welded into line before split rings and flanges are fitted. The valve can be fitted with no additional ‘springing’ of pipework.

Firesafe Design
O-ring seals and metal-to-metal contact on all static joints, graphite rings provide additional resistance to leakage in the event of a fire.

Other Design Features
Anti-blow out stem design shouldering on the body (rather than the bonnet), Automatic cavity relief, Low friction dry stem bearings to minimise operating torques and maximise cycle life. Valves can be supplied with a mounting plate in accordance with ISO 5211 for actuator attachment.

All of the Oliver Twinsafe Valves are tested following our in-house high-performance test specifications, ensuring that our customers receive the highest standard of product.
