Butterfly valve is a common quarter-turn valve, which is mainly used for transport, shut-off and regulating flow. By rotating the handle 90 degrees, the valve stem drives the butterfly plate to rotate to open or close the valve. Butterfly valves can be divided into soft-sealed butterfly valves and hard-sealed butterfly valves by the material of the seals. According to the driving method, the hard sealing butterfly valve can be divided into manual butterfly valve, electric butterfly valve and pneumatic butterfly valve.
In this article, we will introduce you to automated hard sealing butterfly valves. Hope to help you better understand and choose.
Electric hard seat butterfly valve(motorized hard seat butterfly valve) means hard seat butterfly valve equipped with an electric actuator to help flow control remotely or locally. The electric actuator is driven by AC/DC power source and then opens or closes the valve. Available in ON/OFF type, modulating type and intelligent type to help your project be more automated.
● ON/OFF type electric actuator for fully open and fully close. It could feedback the signal to the system once the valve opens or closes fully. Helping you check the situation easier.
● Modulating type electric actuator for regulating the open/close angle of the valve to help flow rate control.
● Intelligent type electric actuator has the same function as modulating type actuator but it has an LCD display to help you control and check the situation locally and easier.
Meanwhile, explosion-proof type actuator, IP68 underwater type actuator, fail-open type actuator and fail-close type actuator are available to meet your special needs.
Features of pneumatic hard seat butterfly valve include low cost, responsive, safe and explosion-proof. Available in single acting(spring return) type actuator and double acting type actuator for your options.
● Spring return type actuator means air to open, and the valve could auto return once the air is interrupted. To keep your project safe.
● Double acting type actuator means air to open and air to close. Responsive and competitive price.
