Is the Spring Check Valve with BSP Female Thread, Type 2281 suitable for use with aggressive chemicals if material compatibility is verified?

Yes — the Spring Check Valve with BSP Female Thread, Type 2281 can be used with aggressive chemicals provided material compatibility is verified. The valve is specified for a wide range of media including chemicals and petrochemical products, but safe use depends on confirming that the brass body, AISI 302 stainless steel spring, brass disc and FKM (Viton) sealing are chemically compatible with the specific aggressive substance, concentrations, temperatures and operating conditions. If compatibility is confirmed for those materials and the valve is installed following flow direction and operating limits (working temperature -10°C to +90°C, appropriate pressure), the Type 2281 offers reliable, long-lasting performance even under demanding conditions.

Can the Spring Check Valve with BSP Female Thread, Type 2281 be installed in vertical piping without affecting its cracking pressure or sealing performance?

Yes. The Spring Check Valve with BSP Female Thread, Type 2281 can be installed in vertical piping without affecting its cracking pressure or sealing performance, provided it is installed following the flow direction marked on the body. The valve is designed for mounting in any position, and its robust brass body, AISI 302 stainless steel spring and brass disc with FKM sealing ensure consistent operation. The valve maintains a constant working pressure across -10°C to +90°C and features very low minimum opening pressures (0.02 bar for 3/8"–2½", 0.1 bar for 3"–4"), so vertical installation will not impair cracking pressure or sealing when chemical compatibility and proper installation orientation are observed.
