2.1 Actuator

A drive device for operating the valve and connected to the valve body. The device may be an electric, pneumatic or a combination of institutions,

Its movement can be stroke, torque, thrust or in combination to control.

2.2 Remote operation of the valve mechanism

The valve actuator or force the hand wheel through the agency telematics to open and close the valve stem on the mechanical force transmission mechanism (Referred to as remote valve mechanism).

2.3 Load test no-loadtest

Valve in the non-operation of media conditions tested.

2.4 Load test

In the medium pressure and the valve operation test in the system operating conditions.
