What are solenoid actuators? Selenoid Equipment used to convert electrical signals or electric currents into mechanical linear motion. Made of the movable coil and iron core. The pulling and pushing strength is determined by the number of turns on the coil. An…
Inspection reasons 1. To protect individuals and equipment Safety valves are installed in process and storage equipment to release pressure that is beyond the limits that cause operating failure, external combustion and other hazards. A good design and properly installed from a…
There are different problems associated with the control valve which affects the flow control. High-pressure drop: The control valve is an obstruction to the flow as a simple orifice plate. The flows through an orifice will accelerate due to its smaller cross-section. …
The control valve is the instrument used to control or regulate the flow of fluid. For controlling of the valve one should know different parameters associated with the control valve. Key parameters that are dynamically measured are described below. Supply Air Pressure:…
Valve guiding is necessary for proper alignment with the seat ring and efficient control of the process fluid. The common method used are listed below: Cage guiding: The cage allows positive alignment and control of the plug. The outside diameter of the…
Pressure relief valves: Pressure relief valves are safety valves that are designed to prevent internal pressure from rising above a predetermined maximum pressure in a pressure vessel exposed to abnormal or emergency conditions. Spring Loaded Design: …
Slide valves are one of the many variations of the gate-type valve and were originally designed for use in the pulp and paper industry to overcome the problems in handling wet and dry fluidized solids in pipelines. The opening…
Noise produced in pipelines may be pump-generated (changes in power and pressure. or varying amplitudes of pressure pulsations) or fluid-generated (flow instability, turbulence or simple fluid friction). Noise caused by the operation of valves, regulators and control elements is transient and related…
Introduction The Level Control Valve with Bi-Level Vertical Float is a hydraulically controlled, diaphragm actuated control valve that controls reservoir filling in response to a hydraulic on/off float pressure command. The Valve opens at pre-set low level and closes at a pre-set…
Introduction The Hydraulically Controlled On-Off Deluge Valve is an elastomeric, hydraulic pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The Hydraulically Controlled On-Off Deluge Valve is activated by a hydraulic relay valve, by which opening…
