Product Features ERWX pneumatic soft seal butterfly valve operating torque is small, is the smallest operating torque in all valves, is the automation control system instrumentation unit, with AC220V, AC380V or DC24V power supply voltage to power from (DCS, PLC ) System or regulating instruments, operators and other input (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, you can control the operation. Rotate the valve shaft by 0 ~ 90 ° with the torque output from the angular stroke to complete the opening / closing action or the adjustment action. All-electric electric actuator adopts the mechatronic structure, with the functions of position feedback, position indication, manual operation and other functions in the machine servo operation and opening degree signal, strong function, reliable performance, simple connection, precise control, small size, weight Light, small flow resistance, large flow coefficient, simple structure, good sealing performance. Adjust the range, through the input current signal or voltage signal, this into a displacement corresponding to the input signal, change the rotation angle of the valve plate (0-90 ° any angle), so a certain input signal corresponding to a certain corner, to achieve Proportional action, so there is a better regulation of control flow and other parameters.

The S(afe)-LOCK safety lock is adhesive-free and has a snap-type gasket connection structure. It is firmly fixed and easy to inspect and maintain. It has an adhesive-free function throughout its life cycle.
The semi-closed gasket groove design technology solves the problem of sealing elasticity release and sealing reliability of the gasket under harsh working conditions such as high pressure and alternating working conditions; at the same time, it effectively isolates the gasket from contact with the atmosphere and media, thereby reducing the gasket's The aging of the gasket is ensured and the service life of the gasket is extended.
The large plate corner holes and the semi-gasket positioning structure design of the secondary sealing area greatly improve the pressure-bearing performance and sealing performance.
Operational safety protection technology, the gasket has four leakage inspection holes at the second seal that are connected to the atmosphere, which can detect medium leakage and reflect the safety protection of stable operation of the equipment.
Unique triangular roof line sealing technology has strong pressure-bearing capacity and more reliable sealing.
