Term Description
Anti-Ligature Recently we have become aware that there is some inconsistency
in the market as to the exact meaning of "anti-ligature". Where we
use this phrase in connection with our products it means that we
have designed and tested the product in order to reduce any risk of
that product being used as a ligature attachment point.
Pneumatic Pushbutton
Control The pneumatic pushbutton control consists of a pushbutton, an
actuator shaft and a housing for the shaft. On the forward stroke,
the actuator shaft pushes against the diaphragm in the diaphragm
actuator.
When the pressure on the pushbutton is released, the shaft travels
in the opposite direction. The diaphragm is released, which lowers
the pressure in the air line tube and a chamber within the air-
operated water valve. This opens the water valve.
Diaphragm Actuator This device is threaded on to the Pneumatic Pushbutton Assembly.
It contains a diaphragm that is moved by the pushbutton actuator
shaft. The differential air pressure is transmitted to the air operated
valve through the air tube.
Air-operated water valve This valve is operated by lowering the air pressure in a chamber.
You can adjust the length of the water delivery cycle from 5
seconds to 5 minutes using the adjustment screw on the valve. The
default setting is 10 to 15 seconds.
Air tube This tube is used to connect the actuator diaphragm to the air-
operated water valve.
BSP The British Standard Pipe (BSP) thread is a family of standard
screw thread types that has been adopted internationally for
interconnecting and sealing pipe ends by mating an external (male)
with an internal (female) thread.
