In addition to cylinders, Luxfer offers a superior line of valves and PRDs (pressure relief devices), including complete cylinder kits for AF applications. Our high-flow PRDs allow a faster release in case of an emergency.
Key features and benefits:
- An extremely lightweight and compact valve with a 6061-T6 aluminum alloy body – up to 50% lighter than similar products.
- Optional studs: fixed or indexable 370 degrees.
- Low-torque for ease of use – up to 66% lower than similar products.
- Includes Luxfer’s high-flow PRD (direct or vented). High-flow in and out (Cv = 2.0; flow equi. =0.277”/7.04mm orifice).
Additional features and benefits:
- Optional excess-flow valve.
- Available rig pin to lock lever in closed position.
- Very low leakage (-50C O-rings).
- Burst: 20,000 psi (1380 bar), 25% higher than other similar products on the market (higher burst ratings available with lower-flow PRDs).
- 200-bar, 250-bar, 350-bar and 450-bar ratings.
- 10,000 cycle life (ISO 15500-4, 250 bar).
- Optional port for remote PRDs, gauges and sensors.
- Compliance to CGA S1.1, NGV3.1, ECE R110 and ISO 15500.
- Patent pending.

Features and benefits:
- Lightweight and corrosion-resistant.
- Allows for cylinder expansion under high pressure.
- Easy to install.
Strap mounts
For G-Stor Go (Type 4) cylinders
These carbon steel brackets were specially designed for Luxfer G-Stor Go cylinders to avoid product damage as cylinders expand while being filled to full pressure.
Features and benefits:
- Strong carbon steel material coated for corrosion protection.
- Specially designed for G-Stor Go 22-inch product range to allow for cylinder expansion without compromising cylinder integrity.
- Easy to install.
- Designed and manufactured to meet NFPA 52 G-loading requirements.
