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.
