Approvals

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

Notes

• Operator options include Manual, Pneumatic, Electric, etc.
• Material options include Carbon Steel, Stainless Steel, Alloy Steel, Etc.

Description

A 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.
