manual valves are those valves that operate through a manual operator (such as a handwheel or handlever), which are primarily used to stop and start flow (block or on off valves), although some designs can be used for basic throttling.
Control valves are valves that provide process control over flow rate, pressure, and temperature in the oil and gas industry. They work by varying the size of the flow passage way as directed by either a hydraulic, pneumatic, or electrical signal sent from a controller.
Steam traps are to discharge condensate, air and other incondensable gases from a steam system while not permitting the escape of live steam. We design and manufacture wide variety of steam traps according to codes and standards.
We design and manufacturer different type of safety valve to open and relieve excess pressure from vessels or equipment and to reclose and prevent the further release of fluid after normal conditions have been restored. A safety valve is a safety device and in many cases the last line of defence.
