Ashford Instrumentation Bar Stock Needle Valve With Lock Off Handle

Ashford Instrumentation bar stock stainless steel needle valve with lock off handle.

The lock off device is an anti-tamper device designed to prevent unauthorised operation of instrumentation valves commonly used for the isolation of pressure gauges and for the regulation or throttling of flow within a pressure system. This product is suitable for the use on liquids, gas or vapour service and fitted as standard with an anti-tamper free-spinning device to prevent unauthorised operation.

The lockable handle is manufactured from glass filled nylon which will not rust and uses a radial pin tumbler locking mechanism that is fully weather and tamper proof. Unlike other security devices, the lock off device can be keyed alike so that multiple valves can be secured with the convenience of having only one key or keyed to differ with up to 50,000 unique combinations available. 

As well as supplying process valves, Ashford Instrumentation Ltd can also supply an extensive range of pressure gauges and pressure transmitters.
