Jual Control Valve

A control valve is comprised of an actuator mechanism that is capable of changing the position of flow controlling element in the valve. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator. The actuator, which can be pneumatically or electrically operated, directs the movement of the stem as dictated by the external control device. (Wiki)

Ability to throttle or control the rate of flow
Lack of turbulence or resistance to flow when fully open - turbulence reduces head pressure
Quick opening and closing mechanism - rapid response is many times needed in an emergency or for safety
Tight shut off - prevents leaks against high pressure
Ability to allow flow in one direction only - prevents return
Opening at a pre-set pressure - procedure control to prevent equipment damage
