GL Type Greaseless
The GL gate valve is a full-bore slab gate valve designed and manufactured in accordance with API 6A and NACE MR-01-75. It is available in standard double flanged, Studded, threaded-end and other special Outlet Connectors and Manual, Pneumatic and Hydraulic operated.
The greaseless gate valve can be widely used in the Fractured wellhead and manifold, etc.
● A ball screw mechanism and lower stem are incorporated into the LS-R gate valve to
minimize the actuating torque.
● The lower stem may be used to indicate the gate position.
● Sealing at the gate-to-seat and the seat-to-body is metal-to-metal.
● In addition to the metal-to-metal seal between the seat and valve body, two spring loaded,
non-elastomeric lip-seals provide maximum 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.
● One-piece seats and slab gate ensure reliable sealing and simplify field service.
● Bi-directional seal technology applied for the gate and seat so as to extend service life.
● The stem shoulder can be backseated against the bonnet to isolate valve cavity pressure,
which makes it possible to replace valve stem sealing under pressure.
● The grease fitting are located on the downstream side of the stem backseat for safety.
● The seal between the valve body and bonnet is a pressure-energized gaskets
● The stem packing is a pressure energized seal and can withstand severe temperatures and fluids.
It is constructed of a non-elastomeric material that offers a low coefficient of friction.
● Bore: 5-1/8"~7-1/16"
● Pressure Class: 15,000PSI ~20,000PSI
● Material Class: AA ~ HH
● Temperature Class: L ~ V (-50℉~ 250℉)
● Product Specification Levels: PSL 1~ PSL 3G
● Performance Requirements：PR 1, PR 2
