this is related to the amount of fluid required in the system. In most cases, the valve is equipped with a scale to indicate the percentage of flow that passes through this valve.
immediately above the stop valve

Emerson Process Management is a manufacturer brand that sells a majority of the control valve actuators on the market today. Other brands include Parker Hannifin Corp., Conbraco Apollo, and Flowserve
Micro-Electro-Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through microfabrication technology
A siphon breaker valve is a small paddle operated butterfly valve designed to automatically control the priming and de-priming of the discharge. It is mounted on top of the discharge pipework siphon loop.
Dear Sir,does it mean "modulating duty",it means can control the valve by a singal. for more informaion,can refer to http://www.valve-actuator.org/Multi-turn-Valve-Actuator/118.html
Hydraulic actuators. Also called hydraulic rams or hydraulic cylinders.
Yes, CPR and defribrillation will work on someone with a mechanical mitral valve.
Your mechanical valve is made of surgical steel. Magnets are attracted to steel.
It shouldnt take long atall maybe maximum 2 hours if you have to alter pipework upstream of the isolating valve
Pneumatic process control valves are used in process industries to control the flow of fluid by using pneumatic actuators. It requires 4.5 to 6 Kg/sq. cm of pressure to operate the valve. Control room sends electrical signals of 4-20 ma to field where I/P converter converts these electrical signals into pneumatic signals. Actuators use these signals to operate the valve. Actuators moves the stem up and down depending upon input signals and control the valve opening. 4ma- 0% opening 8ma- 25% opening 12ma- 50% opening 16ma- 75% opening 20ma- 100% opening
