What gases can the Needle control valve with GW BSP, EWO safely regulate in air installations?

Needle control valve with GW BSP, EWO Format can safely regulate air and other non-flammable, non-toxic gases such as nitrogen, carbon dioxide, helium, argon, etc., in air installations. Its brass body and brass needle, with NBR stem sealing, allow smooth flow regulation up to complete shut-off at working pressures from 25 to 40 bar (depending on DN) and temperatures from -10Â°C to +90Â°C. Direction of flow is marked on the valve body.

Can the Needle control valve with GW BSP, EWO handle liquids or only gases in pneumatic systems?

Needle control valve with GW BSP, EWO Format: This valve is designed for air installations and nonâflammable, nonâtoxic gases (e.g., nitrogen, carbon dioxide, helium, argon). The description does not list liquids; materials (brass body/needle, NBR sealing) and specs (working pressure and temperature) might permit some liquid use, but the product is specified and recommended only for gases. For liquid applications consult the manufacturer for compatibility and sealing suitability.

What is the maximum operating pressure for the Needle control valve with GW BSP, EWO at different DN sizes?

Needle control valve with GW BSP, EWO. Maximum operating pressure by DN size: - DN small (smaller internal diameters): up to 40 bar maximum constant working pressure across the full temperature range. - DN medium: typically up to 35 bar (depending on specific DN). - DN large (larger internal diameters): up to 25 bar maximum constant working pressure across the full temperature range. Operating temperature: -10Â°C to +90Â°C. Body and needle material: brass. Stem sealing: NBR. Suitable for air and non-flammable, non-toxic gases (nitrogen, carbon dioxide, helium, argon, etc.).
