Especially design for the Quick requirements for chemical laboratory VAV control valve. High-speed response and high air tightness, UPVC material, high degree of corrosion, fire resistant. VAV exhaust butterfly valve characteristics:
Body:
1.the valve body using transparent UPVC highly anticorrosive, specifically designed for organic / inorganic fume hood
2.high temperature extrusion molding meet laboratory fire safety requirements
3.shaft with PP material
4.discs PP material
5.butyl rubber seal airtight
Quick actuators
6.the actuator drive mode: high-speed electric actuator stroke one second
7.programmable control action can effectively prevent the actuator continues to adjust itself, which can prolong its life spin
8.actuator feedback control module comes with a microprocessor to achieve high stability
9.straight pipe is not needed for installation
10.Low-noise, which meets or exceed ASHRAE noise requirement
11.Ccontrolled by fume hood monitor, surface wind speed control accuracy: the current set value with surface wind speed 0.5m / s ± 20%
