Product Details

1、 Product Definition

Fireproof vents are installed at the end of ventilation and air conditioning systems with fire protection requirements. In the event of a fire,When the temperature inside the system pipeline reaches 70 ℃, the windClose the mouth and block the fire source at the air supply and exhaust outlet.

2、 Model Description

PYK-FH - (W+250) xH W - Valve nominal width H - Valve nominal height 250mm - Installation of actuatorSpace.

For example:

PYK-FH - (400+250) x400 represents signal feedback power with manual closing, electrically controlled solenoid closing, and valve closing in placeCan.

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 300 ± 15pa,Leakage per unit area ≤ 500m3/(m2);

b. Within the specified fire resistance time (GB/T15930), the static pressure before and after the valve blade is 300 ± 15pa,Leakage rate per unit area ≤ 700m3/(m2);
