Is the Through-hole shut-off valve with GW BSP, EWO suitable for use with nitrogen and other non-flammable gases at up to 25â40 bar and -10Â°C to +90Â°C?

Yes. The Through-hole shut-off valve with GW BSP, EWO is suitable for use with nitrogen and other nonâflammable, nonâtoxic gases (e.g., CO2, helium, argon) within the specified limits. It is intended for air installations and compatible gases, has a brass body, stainless steel AISI 304 ball, NBR stem sealing, and a manual ball closure. Working pressure ranges from 25 to 40 bar (depending on DN) and is constant across the full temperature range. Operating temperature range: â10 Â°C to +90 Â°C. Ensure the chosen DN provides the required pressure rating and verify NBR compatibility with any specific gas under your service conditions.

Can the Through-hole shut-off valve with GW BSP, EWO be installed in compressed air systems with varying flow directions?

Through-hole shut-off valve with GW BSP, EWO Format: Yes - the inline Through-hole shut-off valve with GW BSP, EWO Format is designed for use in air installations and with non-flammable, non-toxic gases and provides a clear flow direction marked by an arrow on the body. It is a manually operated ball valve that seals by rotating the knob until the ball fully closes; correct installation must respect the indicated flow direction to ensure proper sealing and performance. The valveâs materials (brass body, AISI 304 ball, NBR stem sealing), pressure ratings (25â40 bar depending on DN) and temperature range (â10Â°C to +90Â°C) support reliable operation, but reversing flow against the marked direction is not recommended.

Can the Through-hole shut-off valve with GW BSP, EWO be operated manually for precise flow regulation as well as full shut-off?

Through-hole shut-off valve with GW BSP, EWO can be operated manually to achieve full shut-off by turning the knob, which moves the ball until it is completely sealed. However, it is designed primarily as an on/off (shut-off) valve rather than a precision flow-regulation valve. Manual operation allows some degree of throttling by partially turning the knob, but because the closure mechanism is a ball and the valve is intended to stop flow, achieving precise, repeatable small-flow regulation is limited. For accurate and stable flow control use a dedicated control or needle valve; for reliable full shut-off and general throttling in air and non-flammable, non-toxic gas systems (nitrogen, CO2, helium, argon, etc.), the Through-hole shut-off valve with GW BSP, EWO is suitable.

Additional information

Material	B – brass (bronze)

The inline shut-off valve with BSP internal thread is used to stop the flow of the medium in the installation. It is intended for air installations, and it can also be used with non-flammable and non-toxic gases (nitrogen, carbon dioxide, helium, argon, etc.). The closure of the shut-off valve is achieved by manually turning the knob, which moves the ball until it is completely sealed. The direction of flow is indicated by an arrow on the valve body. Maximum working pressure is constant across the full temperature range. Body material: brass. Ball material: stainless steel AISI 304. Stem sealing: NBR. Working pressure: from 25 bar to 40 bar, depending on the internal diameter DN. Operating temperature: from -10°C to +90°C.
