TC300 Protection valve for deep well pumping
Method of Operation
Protection valves of this type for deep well pumping are
controlled by two adjustable magnetic solenoid valves. One
magnetic solenoid valve is normally open when there is no electrical supply and the other is normally closed. In both magnetic
solenoid valves the upper or lower diaphragm chambers are
subjected to the outlet pressure to the pumping system. The
operation of the pump is controlled by the end switch on the
main valve.

Installation Guidelines
• Install shutoff valves on both sides of the pressure sustaining
valves
• Install with flow in direction of arrow on housing
o Protects against damage from coarse dirt
• Note flow direction (indicated by arrow)
• Ensure good access
o Simplifies maintenance and inspection
• The opening period is dependent on the length of the supply
pipework and should be increased if this pipework is extremely long
• The valve of this type cannot prevent excess pressure such
as may be caused by a sudden electrical power failure
o For this purpose a PC 300 surge anticipating valve should
be fitted as well
• Install connectors for removal and refitting for maintenance
