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 a 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 the 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.
