Bailey Birkett G4 Pressure Reducing Valve - Fig 2044

**Refrigeration Gas-Powered Valves: Efficient Control for Industrial Systems** Refrigeration gas-powered valves, also known as gas-operated valves or pneumatically actuated valves, are essential control components used in industrial refrigeration systems. Typically utilised with ammonia (NH₃) or carbon dioxide (CO₂), these valves are actuated by gas pressure, predominantly from compressed refrigerant gas, instead of relying on electrical power. Our refrigeration gas-powered valves are specifically designed for draining oil from collecting tanks within the oil return circuit, ensuring optimal performance and efficiency in your refrigeration systems. **Specifications:** - **Sizes:** Available in 1" to 1.25" - **Connections:** Flanged & Butt Weld - **Materials:** Constructed from either Steel or Stainless Steel - **Medium:** Suitable for glycol-based cold brine refrigerants in accordance with EN 378, examples include NH3, R134a, R290 (propane), R507, as well as blends with refrigeration oil and neutral gas and liquid media. - **Pressure Rating:** PS 40 - **Temperature Range:** -60 to +180 degrees Celsius Max - **Design:** Robust and reliable to meet industrial requirements These valves are engineered to provide superior control and reliability in challenging refrigeration environments, making them an indispensable choice for your industrial applications.

The CONCOA 315 Series is a chrome-plated brass, dual-stage cylinder regulator designed for inert and non-corrosive gases in medical laboratory applications. Its two-stage design ensures stable outlet pressure or flow by compensating for gradual cylinder pressure drops. The regulator provides point-of-use control across five pressure ranges, from 0–15 PSIG (0–2 BAR) to 0–200 PSIG (0–14 BAR). It comes with a standard 2–15 lpm flowgauge calibrated for CO₂ (for lasers and cell growth chambers) or a custom thermal mass flowmeter-calibrated gauge for specific gases. While suitable for medical lab use, it is not intended for therapeutic use in humans.
