Hard seal forged steel ball and the structure characteristics of pneumatic valve products

hard seal forged steel ball and the structure characteristics of pneumatic valve products:
double block and sealing discharge function, the structure of the fire safety, emergency greasing and rescue and reliable pneumatic stem seal;
a, double block and discharge function
hard seal forging steel ball pneumatic 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.
2, automatic pressure release
stay hard seal pneumatic valve pneumatic forging steel ball valve body cavity 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.

3, fire safety structure of hard sealing pneumatic valve pneumatic forging steel ball valve has function of fire safety, its design, manufacture all follow API and API FA specification requirements.
4, sealing emergency greasing care
hard seal forging steel ball pneumatic valve pneumatic valve seat seal due to medium foreign body or fire accident failure, 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.
5, reliable pneumatic valve stem seal and low operating torque
hard seal forging steel ball pneumatic valve sealing ring, in addition to the standards for 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.
6, full size or reducing
hard seal forging steel ball pneumatic valve 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.
7, pneumatic valve stem can be lengthened
hard seal forging steel ball pneumatic valve 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. Eight, flexible operation,

hard seal forging steel ball pneumatic valve 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.
9, drive mode, more easy to realize automation control
hard seal forging steel ball drive mode flexible pneumatic valve, operation mode can choose according to need of manual, pneumatic, electric, gas and liquid linkage, hydraulic, etc.
