Forged Gate Valves
Forged Gate Valves
Kent Forged Steel Gate Valves are compact, sturdy and ideal for high pressure and high temperature applications. These valves are outside screw and yoke types (OS & Y) with a rising stem and non-rising handwheel. These valves must have a bolted or welded bonnet and a full or standard bore. Both are manufactured in accordance with API 602 and ASME B16.34 standards.

Operation | Manual |
- Rugged construction.
- Gate Valve design complies to API 602, ASME B 16.34.
- Suited to handle high pressure and temperatures – up to 425 deg C in carbon steel and 540 deg C in alloy steel.
- The body is forged steel and available in both the full or standard port design.
- The bonnet is forged steel, has an integral backseat and incorporates the stuffing box.
- High integrity – Bolted body-bonnet are provided with spiral-wound stainless steel gasket and graphite filler for high integrity sealing.
- BODY-BONNET JOINT – Two different bonnet joint designs are available. These are either the bolted bonnet or the threaded and seal welded type.
- The wedge, which is solid design, is forged steel and is part of the valve trim. The seating surfaces are ground and lapped.
- Rising stem with precision ACME thread and contains an integral back seat shoulder, which mates with the integral backseat of the bonnet.
- T-head stem-disc connection of Gate Valve fully meets strength requirements of API 602 and API 598.
- The seat rings are pressed into the valve body and wedged into place, forming a seal with the body. The seating surfaces are ground and lapped.
- Two piece gland and gland flange arrangement for reduced stem wear.
- Live loading on packing can be provided as request.
- Nace service either MR-01-75 or MR-01-03 as required.
