402, B40, TusCity, Suzhou Industrial Park, Suzhou, 215122, Jiangsu, ChinaSlab Gate Valve is a special mechanical device used in oilfields and designed to control (close-open) flow stream. Slab Gate Valves are usually used as a component of oilfield equipment, which works under high pressure, such as Christmas tree, wellhead assembly, frac trees, choke manifold, kill manifold, debris catcher, sand filter, cyclone wellhead desander, line heater, etc. API 6A Slab Gate Valves are used during flowback, well testing, oil production. Slab Gate Valve is either operated manually or by hydraulic actuator.
Slab Gate Valve consists of following parts:
· Valve body
· Expanding Gate / Slab Gate
· Lubrication Fitting
· Stem
· Bonnet Seal Ring
· Seat
· Lubrication Fitting
· Thrust Bearings
· Bonnet Packing
· Packing Injection Fitting
· Valve Bonnet
· Handwheel / Actuator
· Lower Bonnet
· Steam Protector
· Lower Steam
· Ball Screw
Slab Gate Valve shall be based on operational and environmental conditions of are where slab gate valve is used.
