The PREL101003 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system at a predetermined pressure, providing essential protection against over-pressurisation within heating systems. The Reliance 101 Series Pressure Relief Valves are widely utilised as a crucial safety feature in sealed heating installations. Upon installation, the valve is calibrated to the correct pressure. If the pressure within the system exceeds this set threshold, the valve automatically opens, releasing water into the atmosphere. This functionality effectively prevents the system from reaching hazardous pressure levels that could potentially cause damage and pose risks to individuals nearby.

Features and Benefits:

• Diaphragm design enhances resistance to scaling, resulting in a longer lifespan.
• The straightforward removal of the single-piece cartridge allows easy access for cleaning or replacement.
• Set relief pressure range from 2.0 bar to 6.0 bar provides flexibility in system design.
• Available with FSBP or MBSP/FBSP connections for optimal installation versatility.
• Exclusively suitable for heating applications.

Specification:

• Size: 1/2" x 1/2"

Ensure the safety and efficiency of your heating system with the PREL101003 Reliance Water Controls Pressure Relief Valve—an essential component for maintaining safe operating conditions.

A marine push button drain valve is a manually operated, spring-loaded valve specifically designed to swiftly drain fluids—typically water, condensate, or small quantities of fuel/oil—from equipment or systems aboard ships. These valves are frequently found in locations where regular and controlled draining is essential, such as air reservoirs, filters, fuel systems, and low points in piping.

Purpose of a Push Button Drain Valve

• Quickly release accumulated liquids (e.g., condensate or water) from:
  • Air tanks and compressors
  • Fuel or oil filters
  • Engine cooling systems
  • Pipe drains or low-point drains
• Prevent system contamination or corrosion caused by trapped water
