Wellhead Gate Valve, Hydraulic Gate Valve
Wellhead Gate Valve, Hydraulic Gate Valve | Reliable Hydraulic Flow Control for Oil & Gas Wells
Product Description
Description
API 6A Hydraulic Gate Valves are crucial components in the oil and gas industry, particularly in upstream operations such as wellheads and production facilities. These valves are designed to provide reliable and tight shut-off in high-pressure and high-temperature environments.
Designed for reliable isolation and flow control, this hydraulic valve can be used as a wellhead gate valve in oil and gas production systems, including wellhead assemblies, Christmas trees and high-pressure production lines. Its hydraulic actuator provides controlled opening and closing, making the valve suitable for operations that require dependable shut-off under demanding pressure and temperature conditions. The full-bore flow passage helps reduce turbulence and pressure loss while allowing convenient access for well intervention and workover tools. With API 6A-compliant construction, metal-to-metal sealing and pressure ratings from 2,000 psi to 15,000 psi, the valve provides a durable solution for onshore and offshore wellhead applications.
Yulin Machinery provides API 6A Hydraulic Gate Valves ranging in size from 1 13/16” to 7 1/16” and pressure ratings from 2,000psi to 15,000psi. API 6A Hydraulic Gate Valve is designed and manufactured in strict accordance with API 6A. Forged or cast AISI 4130/4140 low alloy steel or AISI 410 SS steel, the actuator is designed to be safe and suitable for all kinds of Hydraulic Gate Valves.
Wellhead Gate Valve Features
API 6A Hydraulic Gate Valves Detail
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.
