Product Introduction

Worm gearbutterfly valveEquipped with a labor-saving mechanism - worm gear transmission device, making manual opening and closing of valves easy, especially for large-diameter valves (such as DN1000 and above), which can be operated manually by a single person. Due to the use of deceleration to achieve labor-saving, the opening and closing time of the valve has been extended. The worm gear transmission device is divided into single-stage and two-stage transmission. Our company is equipped with single-stage transmission for DN350 and below, and two-stage transmission for DN400 and above.
