Installation and
operating conditions |
▎安装和操作条件 |
Operating pressure 工作压力:
max. 4 bar (medium pressure)
最大4bar(介质压力)
Control pressure 控制压力:
effective operating pressure + approx. 2.5 bar (closing pressure). If the control or the closing pressure is too high, this will impair the service life of the sleeve. The pressure must not be greater than the required 2–2.5 bar above the operating pressure.
Differential pressure 差压:
control pressure minus operating pressure, max. 2–2.5 bar;
dependent on the rated size and the sleeve quality.
Control medium 控制介质:
compressed air, neutral gases, water, (oil on request).
Temperature range 温度范围:
each sleeve quality has its own specific temperature range.
Permitted ambient temperature from – 20 °C to + 50 °C.
Mounting position 安装位置:
any, with bulk goods preferably vertical. If mounted horizontally, align the control connections upwards.
Function 功能 :
HOmatic pinch valves are pressure-controlled valves. If there is no control pressure, they are open! The valves close if control pressure is applied.
Closing feature 关闭特点 :
HOmatic pinch valves seal gaseous, liquid, pasty and powdery media. The highly elastic sleeve surrounds any solids. A gas-tight seal cannot be guaranteed if the flow medium consists mainly of coarse particles. |
