Can the Foot valve with GW BSP, type 2350 be used with petrochemical fluids given its brass body and NBR seal chemical resistance?

Yes . Foot valve with GW BSP, type 2350 can be used with petrochemical fluids only if those specific fluids are compatible with its materials: brass body and disc, and NBR (nitrile) sealing. The product description explicitly allows use for âpetrochemical products, etc., considering the chemical resistance of the valve material,â so final suitability depends on the chemical compatibility, operating temperature (â10Â°C to +90Â°C) and service conditions. Key considerations: - NBR has good resistance to mineral oils and many hydrocarbons (typical petrochemical fuels and oils) but poor resistance to aromatic hydrocarbons (e.g., benzene, toluene, xylene), some solvents and strong oxidizers. - Brass is generally acceptable for many hydrocarbons but can be attacked by ammonia, strong acids, and some aggressive chemicals. - Ensure operating pressure/temperature remain within the valveâs ratings and that minimum opening pressure (related to suction head) is acceptable for your installation. Recommendation: Check the specific petrochemical fluidâs compatibility with NBR and brass (consult chemical compatibility charts or supplier data). If fluid is compatible and operating conditions fit (temperature, pressure, suction head), Foot valve with GW BSP, type 2350 is suitable; if not, select a valve with a compatible elastomer (e.g., FKM, EPDM) or alternative body material (stainless steel).

Is the Foot valve with GW BSP, type 2350 suitable for use with aggressive chemicals considering brass body and NBR seal?

Foot valve with GW BSP, type 2350 is not generally suitable for aggressive chemicals. Its body and disc are brass and the seal is NBR; while the valve can handle water, some chemicals and petrochemical products, suitability depends on the specific chemical and concentration. Brass is vulnerable to dezincification and corrosion by acids, ammonia, chlorides and some organic solvents. NBR (nitrile) is resistant to oils and hydrocarbons but is attacked by strong acids, ketones, chlorinated hydrocarbons and some solvents, and limited above ~90Â°C. If you plan to use aggressive chemicals, consult chemical compatibility charts for brass and NBR versus the exact substances, concentrations and temperatures; consider valves with stainless steel bodies and chemically resistant elastomers (e.g., EPDM, FKM, PTFE) if incompatibility is indicated.

Can the Foot valve with GW BSP, type 2350 operate in vertical suction lines with flow direction marked on the body?

Yes. The Foot valve with GW BSP, type 2350 can operate in vertical suction lines provided it is installed following the flow direction marked on the body and mounted in a vertical position. The valve is designed for end-of-suction pipeline use in industrial installations (water, chemicals, petrochemical products, subject to material compatibility). It requires a minimum opening pressure proportional to the liquid column above it (e.g., 1.0 bar for 10 m, 0.5 bar for 5 m). Materials: brass body and disc, NBR sealing, BSP female thread. Operating temperature range: -10Â°C to +90Â°C. Maximum constant working pressure applies across the full temperature range.
