Acting British NORGREN Nobel throttle valve definition features

The characteristics of the British NORGREN nornomial throttle valve definition
A throttle valve is a valve that controls the flow of a fluid by changing a throttle section or a throttle length. The throttle valve and the check valve are connected in parallel to form a one-way throttle valve. The throttle valve and the one-way throttle valve are simple flow control valves. In the hydraulic system of the fixed pump, the throttle valve and the overflow valve cooperate to form three throttling speed control systems, that is, the throttle throttle speed regulation System, return oil throttle control system and bypass throttle speed control system. The throttle valve has no flow negative feedback function and cannot compensate for the instability caused by the load change. It is generally only used in applications where the load does not change much or the speed stability is not high.

Characteristics of the British NORGREN Novo Threshold Valve
1. The structure is simple, easy to manufacture and maintain, and the cost is low.
The adjustment accuracy is not high and cannot be used for adjustment.
3. The sealing surface is easy to be eroded and cannot be used for cutting media.
4. The sealing is poor.
UK NORGREN Nobel Installation and Maintenance Throttle Installation and Maintenance
The following should be noted:
This valve often requires operation and should therefore be installed in an easy-to-operate position.
When installing, pay attention to the direction of the media and the direction of the arrow marked on the valve body.
