Vimec Bar stock needle valve
APPLICATIONS
Vimec instrumentation Needle Valve are made from bar-stock and used for installation of pressure switch, pressure transmitters and manometers.
The single isolation valve is metal to metal seat and it is equipped with self centering needle tip for bubble tight shut off and back stop spindle for blowout prevention leakage.
The bonnet design construction do not permit to the process fluid to became in contact with the internal calibration thread, for this reason the Needle Valve performance is guaranteed for long time.
The end connections are available from 1/8" to 1.1/2" size and could be threaded, socket welds or but welds. All needle valves could have female to female, male to male or male to female connections.
Standard packing is P.T.F.E. for temperature up to 180 °C and Graphoil for temperature up to 400 °C.
