Actuators 

Hand wheel or gear box is usually used for gate valve actuation .chain wheel and electric actuator can be also used for gate valve actuator if being requested by the customers .


Back Seating Design
All our gate valves have the back seating design.In most cases,the carbon steel gate valve is fitted with a renewable back seat.For stainless steel gate valve,the back seat is machined directly in the bonnet or is machined after welding .When the gate valve is at fully open position ,the sealing of the back seat can be very reliable .However ,as per the requirement of API600,it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.


Stem Design
The stem is of integral forged design .The minimum diameter of the stem shall per the standard requirement .The connection of the stem and disc is T type .The strength of the connecting area is bigger than that of the T threaded part of the stem .The strength test if that area conforms to API 591.
