WQ-A2F 150Lb/300Lb

Full Port

Size:2"-16"

Features: 1. Advanced seat: seat designed with multiple experiences to ensure valve seal, low friction coefficient, and small operating
torque. Multiple seat materials are widely used.
2. Unerror-free handle: use the flat head stem, and the connection of the handle will not be misaligned, thus ensuring that the
switch the state of the handle indicates the same as the valve.
3. Locking device: in order to prevent the valve switch from misoperation, the valve is fully open and the whole position has a
locking holes to ensure that the valve is in the correct position.
4. Stem anti-flying structure: the stem is mounted to prevent the pressure from flying out, and the metal contact with the valve
the body can be formed after the fire to ensure the stem seal.
5. Anti-static performance: set up springs between ball, stem, and valve body, and can export static electricity generated by
switch process.
6. Refractory structure: various parts (ball and valve body, middle flange, stem, and valve body) are designed to meet the fire
resistance and meet the requirements of API 6FA and API 607.

Benefits:
1. Sealed emergency grease injection. Extraneous substance in the medium or fire causes the accidental failure of valve seat sealing, the grease-injection valve provides a quick connection with the grease-injection gun. The inlet pump easily and quickly injects the sealing grease into the valve seat sealing part, easing the leakage.
2. Reliable valve stem sealing and low operating torque. In addition to the standard sealing ring, an O-shaped sealing ring is also set up on the stuffing cover. Double sealing ensures the reliability of the sealing of the valve stem. Additional graphite stuffing and the injection of sealing grease lower the leakage of the valve stem after the fire to the lowest. The slide bearing and thrust bearing of the valve stem make the valves easy to operate.
3. Full diameter or reduced diameter. According to our needs, we can use structures in full diameter or reduced diameter. The flow aperture of the full-diameter valve is equal to the inner diameter of the pipeline, which is easy for pipeline cleanup.
4. The valve stem can be lengthened. According to the needs of installation or operation, the valve stem can be lengthened. A sanitary ball valve with lengthened stem is especially suitable for urban gas and other occasions that need to have pipelines laid. The size of the lengthened valve stem is determined by the customer's needs.
5. Flexible operation. The use of a valve seat and valve stem bearing with a small friction coefficient and good self-lubricating performance greatly reduces the operating torque of the valve. Therefore, even in the absence of sealing lubricating grease, we can flexibly operate the valve in the long term.
