Hattersley Fig 2910 DN15 PN16 Thermal Circulation Valve - Low Flow

Our Pneumatic Control Valves are expertly engineered to regulate gases, vapours, and liquids, fully compliant with the European Pressure Equipment Directive and certified under the ISO 9001 quality assurance system. Featuring a globe body design, these valves include top-entry, single-seated configurations that operate as either two-way, direct, or reverse action, alongside a multi-spring pneumatic actuator. The innovative modular design of the valve, coupled with an extensive selection of available trims, allows for a multitude of configurations to suit varied applications. When paired with the pneumatic actuator, these valves offer precise modulating control or reliable on/off performance. The actuator can be swiftly converted between direct and reverse actuation without taking the system offline. The expertly crafted body shape ensures optimum flow characteristics to maximise efficiency.

The PREL101016 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 in the event of over-pressurisation. This robust valve is an essential safety feature, primarily utilised in sealed heating systems. Upon installation, the pressure relief valve is calibrated to the appropriate pressure setting. If the pressure within the system increases beyond this threshold, the valve activates, allowing excess pressure to be released into the atmosphere. This action safeguards the system from reaching hazardous pressure levels that could potentially cause damage or pose risks to individuals nearby.

Features and Benefits:

• Diaphragm design enhances resistance to scaling, significantly extending its lifespan.
• The single-piece cartridge allows for straightforward removal, facilitating easy access for cleaning or replacement.
• The adaptable relief pressure range of 2.0 bar to 6.0 bar offers flexibility for various system designs.
• Available with FSBP or MBSP/FBSP connections, providing complete installation versatility.
• Specifically designed for heating applications.
