Needle and Multiport valve Series IV
- 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.
- Through the non-rotating spindle tip, the wear of the sealing elements is reduced. This results, particularly with frequent opening and closing, in a noticeable increase in the service life.
Key features
- Standard material for hydrogen application is 316 with other materials available on request
- 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
- Valve seat tested for leak tightness per BS6755 / ISO 5208 leak rate A
- Customer-specific combination of valves and instruments (hook-up) on request
- Through the blow-out proof design of the valve, working safety is improved, especially in applications with high pressure loading.
