Product description
The GBS Gate Valve is manufactured in accordance with API 6A and NACE MR 0175 and widely recognized as a high quality valve for all types of applications. The GBS is a full-bore, through-conduit valve available in standard double flange, threaded-end and special block body configurations. It is available in pressure ratings from 2000 to 20,000 psi and bore sizes of 1-13/16” to 7-1/16”.
Features :
01.Greaseinjection fitting is located on the bonnet, for lubricating stem, stem nut andgate.
02.Inaddition to the metal-to-metal seal between the seats and gate, GBS gate valvesincorporate two spring-loaded, pressure-energized structures.
03.Thestructure can sense the spring supply load to seal when there is low pressuresand lip seal to seal when there is high pressure. Nonelectrometric lip-sealbetween each seat and the body. This kind of structure protects the metal sealsurface of the seat and gate from damage and improves valve performance at verylow pressures.
04.This double-seal design provides maximum protection againstintrusion of particles into the valve cavity, prevents sand particles from affectingthe metal-to-metal seal between the body and seats and gate and also preventsbody erosion in drilling mud applications.
05.Positivemetal-to-metal sealing (gate-to-seat and seat-to-body).
06.Simple,reliable gate and seat design promotes ease of field service.
07.Bi-directionaldesign provides flow direction versatility and increased service life.
08.Bearingcap grease fitting allows positive bearing lubrication.
09.Stemcan be back seated to allow stem seal replacement with the valve underpressure(For safety purposes, it’s suggested to replace packing after releasingpressure).
10.Metal-to-metalbonnet seal, (pressure energized at 10,000 psi WP and above).
11.Thestem packing is a pressure energized seal and can withstand severe temperaturesand fluids. It is constructed of a non-elastomeric material that offers a lowcoefficient of friction.
12.Compatiblewith a wide range of actuators.
