DESCRIPION OF COMPONENTS
1 The valve seating must be firmly scewed into the
lid ( turns clockwise ). The cap is provided with a key to check the fit of the valve. The inlet valve conforms to the Standard for car tyres.
2 This cuts in if the Polyvessel is pressurized above the red 2.5 bar mark and releases the excess pressure.
3 The working pressure of 2.0 -2.2 bar ( 32 p.s.i. )
is marked with a green line.
3 This cuts in if the Polyvessel is pressurized above the red 2.5 bar mark and releases the excess pressure.
4 This both locks the lid and acts as a pressure release valve. This double function is an additional safeguard against opening the Polyvessel while under pressure. Undoing the mechanical lid lock at the same time opens a pressure release valve, which effects the pressure balance. If the locking lever and the pressure release valve become too easy or too tight to turen, the tension on the conical spring may be wrong.
