Main features: Slab gate valve is an efficient and reliable through conduit gate valve,
with two floating seats to provide a tight seal with the gate. Full bore through conduit design can eliminate flow turbulence. Pressure drop is no larger than through an equal length of pipe.
Design standard :API 6D
Product range :
1.Pressure range :CLASS 150Lb~2500Lb
2.Nominal diameter : NPS 2~48″
3.Body material:Carbon steel, Stainless steel, duplex stainless steel, Alloy steel, Nickel alloy
4.End connection : RF RTJ BW
5.Mode of operation:Hand wheel, Gear box, Electric, Pneumatic, hydraulic device, Pneumatic-hydraulic device;
Product features:
1.Double block and bleed seat design;
2.Operating torque is smaller than normal gate valve;
3.Bidirectional seals, no limitation on the flow direction;
4.When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;
5.Non-rising stem design can be chosen;
6.Spring loaded packing can be chosen;
7.Low emission packing can be chosen according to ISO 15848 requirements;
8.Stem extended design can be chosen;
9.Normally open type or normally close type with through conduit design;
10.Non through conduit design is also available as per customer request
