Features

  • Two parallel gate plates with inter-plate wedging device, replacing the traditional single gate plate design.
  • Sealing elements are separate components, preventing deformation from thermal expansion and temperature differentials.
  • Sealing component materials are wear-resistant and corrosion-resistant.
  • Bidirectional forced sealing capability.
  • Fully enclosed design suitable for all-weather operation.
  • Low operating torque.
  • Rapid actuation.
  • Minimal vibration.

Description

A parallel-gate slide valve with two gate plates and an inter-plate spreading (wedging) mechanism. The pressing force on the seats is regulated by medium pressure acting on a floating gate plate or floating seat, supplemented by the spreading device. Intended for isolation or venting of gases and liquids in pipeline systems.

Selection notes

This slab gate valve is a expanding, parallel gate valve and double disc gate valve pattern, supplied for flanged and butt weld installation.

Sizes run NPS 2" to NPS 60", in PN10, PN16, PN25, PN40, PN63, PN100, PN160, PN250, PN320, PN400, Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500, Class 2500.

The body is offered in Carbon Steel, Stainless Steel and Alloy Steel, so the grade can be matched to the service rather than the other way round.

Stated service media include tap water, sewage, petroleum, chemicals, food-grade media and gas.

It is catalogued for Water & Wastewater and Oil & Gas.

Working temperature is -60°C to 300°C.

Built to ASME B16.34, GB/T 12234, ASME B16.10, GB/T 12221 and EN 558.

Slab Gate Valves configurations

View full Slab Gate Valves system →
This product is part of the Slab Gate Valves modular system. All configurations share the same hydraulically operated body: the control function is set by the pilot valve(s) attached. An existing Slab Gate Valves body in the field can be reconfigured for a different duty simply by swapping the pilot, without replacing the body.
