Product description
The GBFL 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 servic and has many of the same features as the GBS gate valve,including the gate and seat design.
Features:
01.Bi-directional and through conduit design provides low flow residence and increased service life.
02.A ball screw mechanism and balance stem are incorporated into the GBFL gate valve to minimize the actuating torque.
03.Sealing at the gate-to-seat and the seat-to-body is metal-to-metal.
04.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.
05.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.
06.The stem packing can withstand severe temperatures and fluids of fracturing conditions. It’s economical and convenient to maintain.
07.The balance stem may be used to indicate the gate position.
08.The seal between the valve body and bonnet is a pressure-energized, BX-style metal bonnet gasket.
