Product Details
1、 Product Definition
Installed at the end of each branch pipe (smoke inlet) of the mechanical smoke system, it is usually in a closed state and meets the requirements of air leakage. In case of fire or needSmoke exhaust is a valve that is manually and electrically opened to provide smoke exhaust function. Valves with decorative openings or those that have undergone decorative treatment are called exhaust vents.
The smoke exhaust valve version consists of valve body, blades, actuator and other components.
2、 Model Description
FHF①_②_ Ax BA-valve nominal width B-valve nominal height
① -- Product control method:
W: Temperature sensor controls automatic shutdown
S: Manually control to close
DC: Electric control electromagnet closed
DJ: Electric motor turned off
DQ: Electric control pneumatic mechanism closed
② Product Function Code:
F: Equipped with air volume adjustment function
Y: Equipped with remote reset function
K: Equipped with position signal feedback function after valve opening and closing in place
For example:
PYF-SDC-K 400x400 indicates manual opening, electrically controlled solenoid opening, and valve openingThe signal feedback function after opening the position.
3、 Product Features
① Low leakage rate and good air tightness performance;
② Strong anti-corrosion performance and long service life;
③ The valve opens and closes flexibly, and the position feedback signal is accurate;
④ Good fire resistance integrity.
4、 Performance parameters
① Nominal pressure: ≤ 300pa at ambient temperature;
② Applicable medium: air (smoke);
③ Leakage rate: a. At ambient temperature, the static pressure difference before and after the valve blade is 1000 ± 15pa,Leakage rate per unit area ≤ 700m3/(m2);
