DIRECT ACTING PRESSURE REDUCING VALVE

DIRECT ACTING PRESSURE REDUCING VALVE : PRESSURE REDUCI

Direct Acting Pressure Reducing Valve : Ball Water Valve.

Direct Acting Pressure Reducing Valve

pressure reducing


(Pressure Reduction) Reduction of interface pressure, not necessarily below the level required to close capillaries (i.e., capillary-closing pressure).

direct acting


This term has several different meanings depending upon the device it is describing. A DIRECT-ACTING ACTUATOR is one in which the actuator stem extends with an increase in diaphragm pressure. A DIRECT-ACTING VALVE is one with a PUSH-DOWN-TO-C LOSE plug and seat orientation.


In direct acting solenoid valves, the solenoid plunger directly opens or closes the orifice when the coil is energized or de-energized.


Control output action which increases as the process variable increases. In the case of an alarm, a direct acting alarm has its relay activated in an alarm condition.

valve


A device for controlling the passage of fluid through a pipe or duct, esp. an automatic device allowing movement in one direction only


A cylindrical mechanism in a brass instrument that, when depressed or turned, admits air into different sections of tubing and so extends the range of available notes


a structure in a hollow organ (like the heart) with a flap to insure one-way flow of fluid through it


A membranous fold in a hollow organ or tubular structure, such as a blood vessel or the digestive tract, that maintains the flow of the contents in one direction by closing in response to any pressure from reverse flow


device in a brass wind instrument for varying the length of the air column to alter the pitch of a tone


control consisting of a mechanical device for controlling the flow of a fluid
