The PREL104012 High Capacity Potable Water Pressure Relief Valve discharges water off the system at a set pressure in the event of cold water over pressurisation to an unvented cylinder (high flow for larger capacity systems) Reliance Valves 104 Series High Capacity Potable Water Pressure Relief Valve is a high capacity range of pressure relief valves designed to protect an unvented system from over pressurisation. The valves are pre-set and locked to a particular pressure, and if the system exceeds this pressure the valve will lift off the seat and water will discharge from the valve to the waste. The outlet connection is one size larger than the inlet to guarantee the valve will be able to cope with a high capacity discharge. This is the first safety device in line within an unvented system. The valves are available in different pressures ranging from 3.5 - 8 bar, as well as multiple connection sizes to allow for flexible installation. 

Features and benefits: 

- High flow design for larger capacity systems 

- Rapid removal of single piece cartridge for cleaning or replacement 

- Diaphragm design gives improved resistance against scale 

- Protects against over pressurisation 

- Multiple connections for flexible installation 

- Set relief pressure range from 3.5-8.0 bar 

- Suitable for cold water use only

A marine self-closing lever valve is a manually operated valve featuring a spring-loaded lever mechanism that automatically returns to the closed position once the operator releases the lever. These valves are essential in scenarios where a brief, controlled release or sampling of fluids is required — particularly in marine settings to ensure safety and protect the environment.

Purpose of a Self-Closing Lever Valve

• Enables controlled manual release or draining of liquids.
• Safeguards against accidental or unattended open positions.
• Commonly utilised in:
  • Fuel and oil drain lines
  • Tank sampling points
  • Bilge or sludge drains
  • Lube oil system drains
