Composite safety valve PNT-SVP

Price: on request

APPLICATION

The PNT-SVP safety valves are designed for protection against too high-water pressure on electrical water heaters.

Safety valves are designed for nominal pressures of 0.6 MPa, 0.7 MPa and 0.8 MPa.

Safety valves can release following functions:

The safety valve opens the pressure relief port for the outflow of water when the pressure in the tank increase over its permissible limit.
The check valve for filling the heater with water. It also prevents the outflow of water from the
tank back into the supply line in case of pressure failure.
The return valve opens the outflow of water from the tank into the supply line in case of an
excessive pressure rise in the tank exceeding supply line pressure. It makes possible to decrease
the pressure in the tank without uptake of hot water from it.

These valves should be installed in the water supply line of the heater.
The direction of flow should be in accordance with the arrow marked on
The valve body with the pressure relief port downwards.
The water supplying line should be stable to 90°C temperature at least 5 m before heater.
The water supplying pressure cannot exceed the nominal pressure to avoid discharge of water
from the heater.
It is possible to connect the flexible pipe to pressure relief port for discharge of flowing water.
This pipe should have inside diameter 10 mm, max. length 1,2 m and must be stable to 80°C
temperature.
