working medium: mu d, oil, n atural gas(H 2 S)
specification level: PR1~PR2
standardized range: PSL1~PSL4
material class: AA BB CC DD EE FF
code of material: 45K 60K 75K
B.Gate valves are mainly used for control of fluid flow in drilling well control system and drilling fluid manifolds (such as, kill manifolds, choke manifolds, mud manifolds and standpipe manifolds).There are two types of valves: visible and invisible bar type. They can be manually or hydraulically operated.
The model of plate gate valve available is as follow:2-1/16"、2-9/16"、3-1/8"、4-1/16"，rated: 5000psi(35MPa)～15000psi(105MPa.
◆ Low opening torque is needed while under pressure;
◆ End connections are flange, thread or union , and meet the requirements of API;
◆ Valve plates and seats have high hardness and good wear-resistance performance;
◆ Valve is an integral forging with high strength, load-bearing capacity and long service life, and suitable for sour environments including offshore drilling operations.
