Sealing material: nitrile rubber (NBR)
Connection mode: pipe thread G
On-off control for fan coil water flow. The valve body is made of brass, and the driver uses the hysteresis synchronous motor as the driving force. Open the valve, after power failure, there is a spring reset (that is, after the power off the valve itself closed), and is equipped with a manual valve operating mechanism, is the most commonly used central air-conditioning system is one of the electric valve
Valve body:
1, two and three - normally closed flow, DN15, DN20, DN25 of various types
2, brass forging body, stainless steel valve stem and aluminum shell
3, synthetic rubber spool, closed without bubbles
4, normally closed valve Kv (Cv) value can be on-site selection, factory located at the maimum value
5, stainless steel spring reset
Driver
1, can be provided using a high / low voltage model
2, AC hysteresis synchronous motor, low noise, low power consumption
3, manual operating lever
4, graphic design, the movement of the small space occupied by the eternal space
5, can be installed after the valve body
6, the drive can be rotated after installation
