Product Description

API 6A expansion gate valves are primarily used in the oil and gas industry, specifically for wellhead and christmas trees, choke manifold, and other critical service applications where high pressure and temperature resistance are crucial. These valves are designed to provide a reliable and tight shut-off, even in demanding environments with pressure and temperature extremes.

Expanding gate valve utilizes a two-piece gate and segment assembly that expands to create a tight mechanical seal against the valve seats when closed. This design provides a reliable shut-off, particularly in applications where a positive seal is critical.

Enerpal's Expanding gate valve features a non-rising stem with an expanding gate design to provide safe, dependable service in a variety of environments. The expanding gate valves we provide are available with flanged or threaded ends in standard bore Sizes from 2-1/16” through 7-1/16” in working pressures from 2,000 psi through 5,000 psi.

Features of Expanding Gate Valves

Full-Bore Thru-Conduit Design

  • Maximizes valve service life.
  • Eliminates the collection of destructive particles.

Expanding Gate

  • Produces a positive mechanical seal across the seats.
  • Isolates the body cavity from bore pressure in both the open and closed position.

Metal to Metal Seals

  • Press fit or o-ring slip fit seats available.
  • Both have Teflon inserts in the face to form a positive seal against the gate even in low pressure situations.
  • The seats are tightly wedged in the seat pocket when the valve is in the full open and full closed position.
  • Metal-to-Metal Seals Body/bonnet interface, and gate/seat interface.

In-line Repairability

  • Stem packing can be re-energize while the valve is under pressure.

Long Life, Low Maintenance

  • Simple routine maintenance program limits repairs, eases operation, protects against corrosion, and extends service life.
