Needle Valves are used to regulate the flow of a substance – usually gas or liquid – through an appliance or system. What is unique about Needle Valves is the inclusion of a small plunger that is shaped like a needle, hence the name.
Gauge Valves are mainly used to isolate a process from instrumentation such as transducers or gauges and are typically utilised together with block and bleed valves.
A Needle Valve is used for fine regulation of flows whereas a Gauge Valve is used (in most cases) for pressure isolation.
Manually operated threaded Needle Valves are the most common types, however there are also motorised Needle Valves and Angle Needle Valves. Motorised Needle Valves do not require a handle for manual operation and instead use an electric or pneumatic actuator that connects and turns the plunger. Angle Needle Valves commonly turn the output from the inlet in a right angle instead of horizontally.
Needle valves are used for fine control or to metre the flow of the liquid of gas.
Gauge Valves are used to enable pressure between the valve and the instrument to be ventilated once the instrument has been isolated. Thus ensuring that the instrument can be removed safely without any adverse effects from built up pressure.
In selecting a certain type of Needle Valve, you’ll need to take into account the different requirements for your application. This includes pressure, size, material and temperature. The most common materials for Needle Valves are stainless steel or brass. Most Needle Valves are suitable for both low and high temperature applications.
