Needle valves model 8108

Description: Barstock valves are suited to shutting off the impulse line and for mounting pressure measuring instruments. As a standard, the valves feature external stem threads and 1/2 NPT connection threads. Other connections are available on request. For venting the measuring line, the barstock valves have an additional vent hole, which is sealed with a bolt when delivered (see drawings on reverse).
Block and bleed valves also have a separate vent valve.
