Is the Needle valve with GW BSP stainless steel, type H-99 suitable for sampling at temperatures up to 648Â°C with GRAFOIL packing?

Yes. Needle valve with GW BSP stainless steel, type H-99 is suitable for sampling at temperatures up to 648Â°C when equipped with GRAFOIL packing. The product specification states operating temperature up to +648Â°C with GRAFOIL packing, AISI 316 construction, metal/metal sealing, and rated working pressure up to 690 bar, making it appropriate for high-temperature sampling in harsh conditions. Ensure the rest of your system materials and pressure/temperature ratings are compatible and perform application-specific verification and testing before service.

Does the Needle valve with GW BSP stainless steel, type H-99 support metal-to-metal sealing for high-pressure testing up to 690 bar?

Yes. Needle valve with GW BSP stainless steel, type H-99 supports metal-to-metal sealing (AISI 316 steel) and is rated for working pressure up to 690 bar, so it is suitable for high-pressure testing up to that pressure. Note packing seal options (PTFE or GRAFOIL) and operating temperature limits when selecting for specific test conditions.

Can the Needle valve with GW BSP stainless steel, type H-99 be panel-mounted for harsh-condition sampling and testing?

Yes. The Needle valve with GW BSP stainless steel, type H-99 can be panel-mounted for harsh-condition sampling and testing. It is specifically designed for system or panel installation and is intended for use in harsh environments for sampling, flow shut-off, and testing stations. Constructed from AISI 316 stainless steel (body and stem) with metal-to-metal sealing and choice of PTFE or GRAFOIL packing, it supports high working pressures (up to 690 bar) and elevated temperatures (up to +204Â°C with PTFE, up to +648Â°C with GRAFOIL). The valve features a V-type stem (closeâopen operation), factory testing, and BSP female thread connections, all suitable for robust panel-mounted applications.
