Characteristics and advantages of the fixed ball valve

The characteristics of the fixed ball valve

1, double-blocking and emission features: the fixed valve seat using a floating spring preload, regardless of the valve is fully on or off state, on the downstream side of the seat so that fluid blocked valve in the cavity through the discharge of residual materials valve discharge.

2, automatic pressure relief feature: the valve body cavity to stay medium temperature anomalies caused by step-up, the do not pass through safety valve, while the feature alone can be automatic pressure relief valve seats, which ensure that the valve in the transportation of liquid medium Security is very important.

3, fire safety structure: the valve is equipped fire safety features, its design, manufacture were to follow API 607 and API 6FA specifications. Fixed ball picture ball valve fixed ball valve Fixed chart image



The advantages of a fixed ball valve

1, sealing grease for emergency ambulance Note: As the medium of a foreign object or fire accidents caused by the valve seat seal failure, injection valve provided with grease gun greasing the fast connections, easily and quickly sealed grease is injected into the valve seat seal parts, ease the leakage .

2, reliable stem sealing and low operating torque: In addition to setting the standard sealing ring, the packing gland has also set up "O"-rings, double sealed to ensure the reliability of the valve stem seals; addition of graphite filler and sealing grease to make a fire after the injection of stem leakage to a minimum. Stem sliding bearings and thrust bearings so that the valve operation of the Light.

3, Full Bore or reduced bore: according to the need to use the whole path or necking structure. Full Bore Valve flow aperture in line with the pipeline diameter, easy to clean pipelines.

4, stem can be lengthened: According to the installation or operation of the necessary, can be extended to the valve stem. Plus long-rod valve is especially suitable for urban gas pipelines that require the laying of underground occasions. Long stem size according to customers need to be identified.

5, flexible operation: Using a small friction coefficient and good self-lubrication of valve seats and valve stem bearings, greatly reducing the operation of the valve torque. Thus, even in the case did not provide sealing grease, it is also the long-term flexibility to operate freely against the valve ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve ball valve V Type Ball Valve
