Niezgodka Type 66 Open Discharge Safety Valve

Refrigeration thermostatic 3-way valves play a crucial role in regulating the flow of refrigerant within refrigeration systems. These valves enable precise control over the temperature and pressure in various system components. They are particularly beneficial in applications requiring accurate refrigerant flow management, such as air conditioning systems, chilled water setups, and industrial refrigeration units. Additionally, they are essential for maintaining the oil temperature of compressors and circuits at a stable level.

The Reliance Valve's Anti-Legionella Valve is specifically engineered to safeguard against harmful bacteria like Legionella by ensuring continuous water circulation and eliminating stagnation in stored cold water within expansion vessels. Available in a variety of sizes, this valve is suitable for applications ranging from point-of-use water heater expansion vessels to larger plant room storage tanks. By converting a standard single connection expansion vessel into a ‘flow-through’ type, the Anti-Legionella Valve diverts part of the flow into the vessel, thereby continuously renewing the water and reducing the likelihood of stagnation that can lead to bacterial growth.

Features and Benefits:

• Keeps water circulating through the expansion vessel
• Prevents water stagnation
• Simple installation process
• Integrated ball valve and drain valve for hassle-free servicing and maintenance
• Compatible with any standard vessel featuring 1/2", 3/4", 1" or 1 1/4" connections
• Designed exclusively for cold water applications
• Only suitable for use with copper piping
• Anti-Legionella models ANTI110003 and ANTI110004 include a locking mechanism

### Features & Benefits - **One-Way Flow Control**: Our check valves allow flow in a single direction and automatically close if the flow reverses, ensuring reliable operation based on pressure and flow velocity. - **Non-Slam Design**: The innovative rubber seat combined with a spring-assisted closure mechanism minimises slamming, enhancing the longevity of the valve. - **Quiet Operation**: The EPDM rubber seat ensures quiet functionality while improving the seating of the disk, resulting in smoother operation. - **Eyebolt Compatibility**: For sizes DN200 and above, the valves feature tapped holes for eyebolts in compliance with BS EN ISO 3226: 2010 (eyebolts are not included). - **Versatile Applications**: This valve is specifically designed for pump duty applications, making it an ideal choice for various systems. ### Specification - **Dimensions**: The face-to-face dimensions meet the standards outlined in BS EN 558 series 16. - **Installation Flexibility**: Suitable for installation in both vertical and horizontal pipelines. Note that when installed in vertical pipelines, the flow must always be directed upwards. - **Regulatory Compliance**: This valve is meant for use with group 2 liquids only, as defined by the Pressure Equipment Directive 2014/68/EU. ### Pressure/Temperature Rating - **Figure 861**: Rated for PN16 - **Temperature Range**: Operational from -10°C to 120°C Optimise your fluid control systems with our reliable check valves, designed for safety, efficiency, and compliance.
