Gate Valves are available in six different types :

• Wedge type Bolted Bonnet

• Wedge type pressure seal bonnet

• Parallel Slide Bolted Bonnet

• Parallel Slide Pressure Seal Bonnet

• Conduit Bolted Bonnet Slab Gate

• Conduit Bolted Bonnet Expanding Gate

Cryogenic Service

Gate Valves can be designed in a special version suitable for cryogenic service. In this case, all the materials and technical features are designed to withstand minimum design temperature required by the Customer, down to Cryogenic -196°C. If required by the customer, specific Cryogenic Tests are performed to verify the behavior of production valves in terms of valve torque, sealing capability, emissions vs the ambient.

UL/FM GATE VALVES

Resilient wedge gate valves have features to make them easier to operate, preserve sealing capability, and interior coating integrity for many years of reliable service. Numerous designs and end connections are available that meet stringent UL/FM requirements, some with maximum working pressures of 350psi. In addition to popular end connection options, these valves can be ordered with system that incorporates an O-ring sealed compression connection and integral pipe restraint in one “ready to use” easy and quick to install package.
