ZFV Pneumatic Ball Valve DN80 PN16 Flange ends stainless steel delivered to client .  .   


Below technical data for reference :

Nominal size DN80,pressure rate PN16, connecting type flanged end, the pipe flange as per GOST 33259-2015, floating ball construct. It’s a kind of on-off ball valve, main part material is austenic stainless steel: body ASTM A351 CF8, ball ASTM A182 F316, stem ASTM A182 F316, seats material PTFE, the valve leakage class is GOST 9544 - A, valve operated by single action pneumatic actuator, with manual override, the actuator failure position is closed ( normally closed valve ). With solenoid valve, with air-filter. With air-pipe and fittings. The valve can be installed in low ambient temperature.


The ball valve flange drilling is according to GOST 33259-2015, the every ball valve tested and inspected by hydro / water for shell and high pressure seat sealing, and air test for low pressure seat sealing.


For this this stainless steel ball valve , we do not apply painting since client do not have special requirement.


The solenoid valve model and air-filter is used for client’s detail request . the bracket installed to top of actuator by NAMUR standard, so that client can install limit switch more convenient .


The floating ball valve was tested, no visual leakage found during hydro testing and air testing, meet requirement of GOST 9544-A class. dimemsions checking and function checking result is ok .

The detail value of testing pressure as below :

1.5 times by PN which is 2.4Mpa by hydrostatic ( water ) for shell testing.

1.1 times by PN which is 1.76Mpa by hydrostatic ( water ) for high pressure closure testing.

0.6Mpa by air testing for for low pressure closure testing.
