How Gate Valves Work ?
Gate valves work by inserting a dam (“gate”) into the path of the flow to restrict it, in a manner
Control Valves

How Diaphragm Valves Work ?
Diaphragm valves use a flexible sheet pressed close to the edge of a solid dam to narrow the flow path
How Sliding Stem Valves Work ?
A sliding-stem valve body is one where the moving parts slide with a linear motion. Some examples of sliding-stem valve
Why Restriction Orifice is some distance from Blowdown valve ?
Very basic does not imply obvious…i really like this statement. Very often the answer is very fundamental and basic to
Disassembly of Sliding-stem Control Valve
The following collection of photographs chronicles the complete disassembly of a Fisher E-body globe valve with pneumatic diaphragm actuator. This
What is ON/OFF Valve ?
An ON/OFF Valve is the fluid equivalent of an electrical switch, a device that either allows unimpeded flow or acts
Trip Valve Principle
Pressure‐sensing trip valves are for control applications where a specific valve/actuator action is required when supply pressure falls below a
Pilot-operated Relief Valve Principle
Like other pressure relief valves (PRV), Pilot operated relief valves (PORV) are used for emergency relief during overpressure events (e.g., a tank gets too
Pressure Relief Valve Principle
A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build
Dome Valve Working Principle
Dome Valve is a pressure tight compressed air operated valve, capable of returning over one million maintenance-free cycles, even in abrasive,
