Hydraulic Gate Valves
Operating temperature
Hydraulic Gate Valves can provide API 6A temperature class L (-50 F) to Y (650 F). According to the requirements of Appendix G of the latest version of API 6A, the pressure of valves used for API temperature classes X and Y is reduced.
Expand the door
Hydraulic Gate Valves can be replaced on site and provide tight mechanical seals that do not rely on pipeline pressure. This ensures the integrity of the seal under high pressure and low pressure.
Seat design
The standard valve seat gate and the sealing interface of the valve seat and the body adopt a sliding fit design, assisted by plug-ins on the front and back of each valve seat. Metal-to-metal gate-to-seat and press-fit valve seat-to-body seals are used for high temperature valves, otherwise it can be provided on request.
Package Design
Chevron-style stem packing is replaceable and can be re-energized by filling between packing stacks. This ensures effective sealing during the life of the valve. Graphite fillers are used for high temperature applications.
Body lubricant
All Hydraulic Gate Valves are supplied with valve body filling grease suitable for the valve material grade and temperature rating to ensure smooth operation of the valve under pressure and prevent corrosion during storage before deployment.
Grease accessories
The valve body can be lubricated by a grease nipple provided in the valve body. All accessories meet the requirements of NACE MR0175.
Exposed bolt
All exposed bolts meet the requirements of NACE MR0175.
Full-through pipe hole
The full-through duct hole provides smooth flow and minimal turbulence. It also provides unimpeded access for workover tools.
