Pneumatic Control Valve

Introducing our Stainless Steel Expansion Vessel for potable water applications, the Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessel. This expertly designed vessel efficiently accommodates the additional load within a water system as the water heats and expands. Crucially, it helps maintain safe operating levels by preventing pressure build-up in both sealed heating systems and cold water systems. Featuring a replaceable membrane, the vessel safeguards the water from corrosion and contamination, ensuring it remains safe for human consumption. The replaceable membrane also allows for straightforward servicing without the need for removal, enabling quick and efficient maintenance in situ.

Features and Benefits:

• Durable stainless steel bolted flange that resists corrosion
• Extra-wide membrane opening to minimise noise from restricted flow
• Internal membrane ensures no water contacts the steel shell, preventing internal corrosion
• Available in a wide range of sizes from 2 to 5000 litres, catering to all applications
• All models come with a replaceable membrane for easy servicing without removal
• Pre-charge valve for convenient air pressure adjustment
• Designed for use with hot and cold water only

The CONCOA 429 Series four-port stainless steel regulator provides single-stage primary pressure control for ultra-high purity gases or applications requiring face seal connections. Ideal where minor outlet pressure fluctuations are acceptable, it features a metal-to-metal diaphragm seal, CAPSULE® 360° filtration, butt-welded face seals for maximum leak integrity, pipe-away relief, captured vent-capable bonnet, and front/rear panel mounting. Specs: max inlet 3000 PSIG (210 BAR), PTFE seats, 10 µm stainless steel filter, 1/4 in face seal ports, 2 in gauges, Cv 0.1, -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, CRN OH5216.

### 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.
