Is the Pneumatic Emergency Shut-Off Valve, HoseGuard® compatible with my system’s pressure (4–18 bar) and connection types (GZ/GW BSP)?

Yes. The Pneumatic Emergency Shut-Off Valve, HoseGuard® is compatible with your system’s pressure range and connection types. It has a minimum operating pressure of 4 bar and a maximum working pressure of 18 bar, matching your 4–18 bar requirement. Connection options include GZ (male) BSP or GW (female) BSP inlet with a GW BSP outlet—select the appropriate inlet type to match your fittings. Also confirm flow rate, hose length/diameter and internal installation dimensions to ensure correct selection; Tubes International offers expert support if needed.

Can the Pneumatic Emergency Shut-Off Valve, HoseGuard® protect against hose bursts in installations with long hose runs or large bore diameters?

Yes — the Pneumatic Emergency Shut-Off Valve, HoseGuard® can protect against hose bursts in installations with long hose runs or large-bore diameters, provided it is properly selected and sized for the specific application. The device is certified to relevant safety standards (EN 983, EN 4414, ATEX Group II, TÜV) and is built for robust performance (aluminum body, POM or aluminum piston, stainless-steel spring, NBR seals) with operating parameters of 4–18 bar and −20°C to +80°C. Key considerations: - Selection must account for required flow rate, hose length and internal diameter, and overall installation geometry to ensure rapid and complete shut-off. - Connection options (GZ BSP or GW BSP inlet, GW BSP outlet) and internal dimensions affect performance in long runs or large bores. - For installations pushing the limits (very long lengths, very large diameters, or atypical internal layouts), expert sizing and confirmation are recommended. Tubes International offers professional support to size and recommend the optimal Pneumatic Emergency Shut-Off Valve, HoseGuard® for your specific system.
