Thermocouple Construction
A thermocouple is constructed of two dissimilar metal wires joined at one end. When one end of each wire is
Resistance Temperature Detectors (RTD) Construction
The RTD incorporates pure metals or certain alloys that increase in resistance as temperature increases and, conversely, decrease in resistance
Applications of Needle Valves
A needle valve is a type of valve having a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only
Blowout preventer (BOP) Principle
A blowout preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the
Flame Arrester Principle
A flame arrester (also spelled arrestor), or flame trap is a device that stops fuel combustion by extinguishing the flame.
What is Shutdown Valve?
A shutdown valve (also referred to as SDV or Emergency Shutdown Valve, ESV, ESD, or ESDV) is an actuated valve
