Válvula de control

The control valve is composed of two main assemblies: valve body assembly and actuator assembly (or actuator system). Mientras tanto, there are four series: single seat series control valves, double seat series control valves, sleeve series control valves and self operated series. There are different types of control valves, and their applications are different. Por lo tanto, selection of the type of control valves should be reasonable according to the requirements of the process. Especialmente, fire control valves are also one of them.

What is control valve?

As well known, the control valves will control the water flow in the sprinkler system. Además, the control valves should always be in the open position, despite some unique exceptions (p.ej., the control valve in the fire pump test header). Otherwise, we could do the operation of close of the valves when system repair, testing or maintenance. According to NFPA, closed valves are the main cause of sprinkler system failure. There may be several control valves in the whole system to divide the system into specific parts. These valves are available in various sizes and types.

Difference from butterfly type and control valve

Butterfly valves and control valves are two types of valves, which are often used in various processing applications. The control valves, also known as the control nozzle, is a valve used in many industries. Por ejemplo, fire-fighting industry. Mientras tanto, fire protection control valves are to control the flow of water or foam according to the command input on the controller. Las válvulas de control de protección contra incendios también pueden cambiar el tamaño del canal por el que fluye el fluido a través del sistema..
