Manual leverPneumatic single-actingElectric 230V AC

Features

  • Low fluid resistance; internal medium channel is straight-through with no change in flow direction
  • Pressure self-tightening seal; sealing performance increases with pressure
  • Valve body ends typically joined by butt weld
  • Low operating torque for opening and closing
  • Simple body structure
  • Good sealing performance
  • Reduced erosion of seating surfaces when fully open
  • Bi-directional flow capability; suitable for installation in either orientation
  • Long closing time reduces risk of water hammer
  • Guide mechanism in valve body prevents gate rotation during operation, ensuring accurate seating surface alignment
  • Gate does not contact seat until final closure, reducing seat wear
  • Generally installed horizontally in pipeline

Description

High temperature and high pressure slab gate valve featuring a grooved flange with a self-tightening seal structure, where sealing performance increases with pressure. The valve body incorporates a guide mechanism to prevent gate rotation during operation, ensuring accurate seating surface alignment. The gate does not contact the seat until final closure, reducing wear and extending service life. Generally installed horizontally in the pipeline.

Selection notes

This slab gate valve is a high temperature high pressure gate valve and wedge gate valve pattern, supplied for flanged and butt weld installation.

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.
