API 600 | ANSI B16.34 | EN 12516. A GATE VALVE cast steel body. Trim as per API 600.



Gate valves are one of the original valve designs and are ideally suited for severe duty on/off applications. Through conduit slab and expanding gate valves provide superior sealing characteristics to any other type of valve configuration making them the ideal choice for high integrity and zero leakage subsea applications. The superior sealing forces due to the larger sealing area also makes a gate valve more suitable for higher pressures even in combination with high temperatures. In addition the fast closing mechanism makes the gate valve ideal for quick acting safety applications like HIPPS.

When determining which solution to specify, gate valve or ball valve, the end to end dimensions will often factor, especially when weight is also a restriction. Here, clearly due to the inherent design, gate valves may offer a superior solution, as opposed to a height critical choice which may favour a ball valve design. However if height is also an issue , for example in well applications, there are alternative gate valve configurations to consider i.e. a rising stem design– outside screw, which tends to be ‘taller’ or a non-rising stem – inside screw design which tends to be ‘shorter’ and more compact.



  • Universal use for temperature up to 649°C
  • Fluid tightness achieved by fluid pressure, not from mechanical action thus eliminating thermal binding
  • Ideal for processes with large temperature variation
  • Perfect tight shut-off in either directions
  • Self-aligning fully supported discs
  • Flexibility compensates for seat face distortion
  • Inherent self-cleaning action

Other remarks 1 The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
Other remarks 2 SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing
Other remarks 3 Rising stem structure, making the valve switch position be clear at a glance
Other remarks 4 The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.
Other remarks 5 Small switching moment, reliable sealing
Other remarks 6 The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.
Other remarks 7 Small flow resistance, high flow capacity and good flow characteristics
Other remarks 8 For small gate valves, the interchangeability can be ensured with process tooling.
Other remarks 9 Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.
