Fixed pneumatic ball valve characteristics and advantages

fixed pneumatic ball valve features:

and double block and emission features: fixed pneumatic ball valve adopts floating pneumatic seat spring preload, regardless of the pneumatic valves are in a state of full open or close, upstream and downstream side of the pneumatic valve seat make fluid blocking, pneumatic valve body lumen retentate by pneumatic valve discharge.

function, automatic pressure release: pneumatic valve body cavity for medium temperature increase caused by the abnormal pressure, do not need through the security pneumatic valve, pneumatic seat function is only can automatic pressure release, the guarantee the safety of pneumatic valve in liquid medium is very important.

, the structure of the fire safety: pneumatic valve has function of fire safety, its design, manufacture all follow API and APIFA specification requirements.

the advantage of fixed pneumatic ball valve:

and sealing emergency greasing rescue: as the foreign body in the medium or fire failure, a pneumatic seat tightness caused on the pneumatic valve provides a connection to a quick note grease gun, convenient and quick to sealing grease injection to the pneumatic valve seat sealing parts, reduce leakage. Fixed pneumatic ball valve features and advantages

pneumatic valve stem seal, reliable and low operating torque: in addition to setting the standard of sealing ring, the packing gland is also equipped with the 'O' type sealing ring, double seal to ensure the reliability of the pneumatic valve stem seal; Adding graphite packing and sealing grease injection make pneumatic valve stem leakage after the fire to a minimum. Pneumatic valve rod sliding bearing and thrust bearing pneumatic valve operation.

and full size or reducing: can choose according to need full size or reducing structure. All sizes of pneumatic valve flow aperture is consistent with the pipeline diameter, facilitate pipeline cleaning.

, pneumatic valve stem can be lengthened: according to the needs of the installation or operation, can be extended to pneumatic valve pneumatic valve stem. Extension rod pneumatic ball valve, especially suitable for the occasion of city gas and so on need to be buried laying pipelines. Extended pneumatic valve stem size according to customers need to be addressed.

, flexible operation, has a small friction coefficient and good self-lubrication pneumatic seat and pneumatic valve rod bearing, greatly reduced the pneumatic valve operating torque. So even in the case of the provided no sealing grease, is also a long-term mobility of pneumatic valve operation.
