Bi-directional and through conduit design
A ball screw mechanism and balance stem
Sealing at the gate-to-seat
The seat-to-body is metal-to-metal.
Description
This Gate Valve was designed for use as a manual valve in high pressure, large bore applications. This valve incorporates a lower balancing stem and unique ball screw mechanism for ease of operation in the field. It is value-engineered for reliability, low torque, ease of operation and service.
Features
-Bi-directional and through conduit design provides low flow residence and increased service life.
-A ball screw mechanism and balance stem are incorporated into the GBFL gate valve to minimize the actuating torque.
-Sealing at the gate-to-seat and the seat-to-body is metal-to-metal.
-One-piece seats and a slab gate ensure dependable sealing and simplify field service. The gate and seat assembly seals in both directions, and the gate and seats can be reversed for increased life.
-In addition to the metal-to-metal seal between the seat and valve body, non-elastomeric seal rings provide protection against intrusion of particle contaminates into the valve cavity, improve gate and seat service life, prevent damage to the body-to-seat seal face, and improve valve performance at very low pressure.
-The stem packing can withstand severe temperatures and fluids of fracturing conditions. It’s economical and convenient to maintain.
-The balance stem may be used to indicate the gate position.
-The seal between the valve body and bonnet is a pressure-energized, BX-style metal bonnet gasket.
