Needle valves and multiport valves separate the process from measuring instruments such as pressure gauges, switches or transmitters. By closing this valve the instrument can be safely dismounted for services like recalibration or replacement. With the vent connection option, the instrument can be vented to the atmosphere by means of the needle valve. Already in the standard version, the multiport valve is equipped with two additional connections. These can be used either as vent connections or for the connection of additional instruments.

Special features of the needle valve
Low-wear design due to non-rotating spindle tip in the bonnet
Low torque and smooth operation of valve handle even at high pressure
Enhanced safety due to blow-out proof bonnet design
