Open/close transmitter butterfly valve DD71X-16C/DD371X-16C

Introduction to the butterfly valve of the opening and closing transmitter:

DD71X-10/DD71X-16/DD371X-10/DD371X-16/DD71X-10Q/DD71X-16Q/DD371X-10Q/DD371X-16Q/DD71X-10C/DD71X-16C/DD371X-10C/DD371X-16C/DD71X-10P/DD71X-16P/DD371X-10P/DD371X-16P/DD71X-10R/DD71X-16R/DD371X-10R/DD371X-16RThe butterfly valve of the opening and closing transmitter is used in pipelines of petroleum, chemical, food, papermaking, hydropower, shipbuilding, water supply and drainage, smelting, energy and other systems. It can be used as a regulating and throttling device on various corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. Specially suitable for high-rise building fire protection systems and other pipeline systems that require displaying valve switch status. This valve is generally installed horizontally. Suitable for controlling valves in fire protection systems that require constant opening. When the valve is opened or closed to its position, the signal device on the valve can send a signal to the fire detection center to display whether the butterfly valve is open or closed, in order to prevent the valve from accidentally closing and affecting the automatic sprinkler fire extinguishing function

Product features:

1. Small and lightweight, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, with rapid opening and closing of 90 ° rotation.

3. Small operating torque, effortless and lightweight.

4. Achieve * sealing and zero gas test leakage.

5. Selecting different component materials can be applied to multiple media.

6. The flow characteristics tend towards a straight line, with good regulation performance.

7. The opening and closing test can be conducted up to 10000 times, with a long service life.

8. All pipelines that use gate valves, check valves (ball shut-off valves), globe valves, plug valves, rubber hose valves, and diaphragm valves, especially in high-rise building fire protection systems and pipeline systems that require valve on/off status display, can be replaced with this valve.
