Construction
The foot valves and non-return valves have internal
thread and consist of valve casing, upper and lower
part for MV or valve casing and strainer for BV. The
valve seat consists of a stainless-steel ring on which
rubber has been vulcanised. Due to this construction,
the valve cone is seated directly on the stainless-steel
ring at high pressures to relieve the pressure on the
rubber.
To seal the valve, the valve cone is spring-loaded and
controlled by guides in both the upper and lower part of
the valve casing.
