2-1/16" 5000PSI API 6A Expanding Gate Valve
The expanding gate valve is a bi-directional valve with a preferred sealing side, which is specifically designed for applications on wellheads, production trees, and manifolds. It is capable of operating under working pressures at or below 5000 psi.
This expanding gate valve complies with the requirements of the latest edition of API 6A. In addition, it can also meet the requirements of API 6A SSV (Surface Safety Valve) by replacing the expanding gate with a slab gate.
Moreover, the materials used for this valve are suitable for services involving H₂S, in line with the latest edition of NACE MR0175 standard, ensuring its excellent performance and reliability in harsh environments with hydrogen sulfide presence.
Bi-directional Sealing: This valve is bi-directional but has a preferred sealing side, capable of providing good sealing performance in both directions and effectively preventing fluid leakage.
Low Operating Torque: With an optimized design structure, the valve requires less torque during the opening and closing processes, making the operation easier and more convenient, reducing the operating difficulty and labor intensity.
Metal-to-Metal Sealing: The metal-to-metal sealing method is adopted between the valve body and the valve bonnet, which has good sealing performance and pressure resistance. It can maintain a stable sealing effect under high-pressure environments and avoid the leakage risk caused by the aging or damage of sealing materials.
Lubrication Design: Equipped with a lubrication device, the valve can be lubricated regularly to reduce friction between components, extend the service life of the valve, and reduce maintenance costs. Meanwhile, the grease can also play a certain sealing role, further improving the sealing performance of the valve.
Gate Plate Guide Design: The gate plate is equipped with a guide device, which can ensure the stability of the gate plate during the lifting and lowering processes, avoid jamming or wear between the gate plate and the valve seat, and also help maintain the sealing performance of the valve. In addition, the gate plate guide device can retain the lubricant inside the valve body to protect the surface of the gate plate and reduce corrosion and wear.
Multiple Operation Modes: Manual or actuator operation can be chosen to meet the needs of different working conditions and users. Manual operation is simple and convenient, suitable for on-site operation; actuator operation can achieve remote control and automated operation, improving work efficiency and operation accuracy.
Simple and Economical Design: The overall structural design is simple, with a relatively small number of parts, reducing production and maintenance costs. Meanwhile, it also improves the reliability and stability of the valve and reduces the probability of failures.
Multiple Connection Methods: It provides multiple connection methods such as flange connection and threaded connection, facilitating connection with different types of pipeline systems and improving the universality and applicability of the valve.
Valve Body Materials: Usually, high-strength carbon steel, alloy steel and other materials are adopted, which have good mechanical properties and corrosion resistance and can withstand the tests of high pressure and harsh environments.
Sealing Materials: According to different working conditions and medium requirements, appropriate sealing materials can be selected, such as metal seals, soft seals, etc., to ensure the sealing performance of the valve under various medium and temperature conditions.
Corrosion Resistance: It complies with the NACE MR0175 standard and is suitable for the oil and gas extraction and transportation environments containing corrosive media such as H₂S and CO₂, effectively resisting corrosion and extending the service life of the valve.
Operating Temperature Range: Generally, it can work normally within the temperature range from -20°C to 120°C, meeting the environmental temperature requirements of most oil and gas fields.
Regular Inspection: Regularly inspect the valve, including appearance inspection, sealing performance inspection, lubrication condition inspection, etc., to discover and deal with potential problems in a timely manner and ensure the normal operation of the valve.
Lubrication Maintenance: Lubricate the valve at the specified time intervals, keep the grease sufficient and clean, and avoid component wear and failures caused by poor lubrication.
Cleaning and Maintenance: Regularly clean the valve to remove dust, dirt and corrosion products on the surface, prevent impurities from entering the inside of the valve and affecting the sealing performance and operation performance of the valve.
Replacement of Wearing Parts: Timely replace the worn or damaged wearing parts, such as seals, packing, etc., to ensure the sealing performance and reliability of the valve.
Operation Specifications: Strictly operate the valve in accordance with the operation procedures, avoid excessive force or misoperation and prevent damage to the valve.
