Through Conduit Expanding Gate Valve Body
We could manufacture all kinds of gate valve body according to our customers' requirements.
Through Conduit Expanding Gate Valve
This type of valve includes in itself the features of a through conduit service and of a standard gate valve with a parallel seating surface.
Construction is available with single expanding or double expanding system. In the first case, the two halves of the gate are pushed against the seats in the valve closed position by having an internal stop acting on one of the two halves. In the second case the same expansion is also obtained in the valve open position.

Technical Specification

Design and manufacture standard: API 6D/ASME B16.34
Face to face standard: API 6D/ASME B16.10
Pressure-temperature rating standard: ANSI B 16.34
Flange end dimension standard: ASME B16.5/ASME B16.47
Welded ends dimension standard: ASME B16.25
Inspection and test standard: API 6D/API598

1. Materials:
Carbon steels, low temperature carbon steel, austenitic stainless steels, duplex and superduplex stainless steel and nickel alloys.
Standard of reference is API 6D full bore.
2. Pressue classes:
The pressure classes are normally ranging from 300#, 600#, 900# to 1500#, to 2500#.
Pressure classes meet ANSI standard.
3. Size:
Size range depends on pressure class rquirements.

Design Features
1. Valve position indicator
The indicator shows the gate position while operating the valve, it is easy for the operator to know how much space of the bore has been opened or closed.
2. Dust proof design
The stem packing is installed inside the bonnet; The outside dust is isolated by bonnet. At the same time, the packing is easily tightened by the bonnet.
3. Stem and seat sealant injectors
4. Zero leakage between body and bonnet
5. Float seats
The seat with springs loaded and the double O-ring seal design ensure the gate and seat to contact perfectly. At the same time, this design make the valve have double block and bleed and pressure automatic relief functions.
6. Double block and bleed function(DBB)
7. Fire safe design
8. Bi-directional
9. Easy to maintain without removing from pipeline
