BuTech Pipe Check Valves | High-Pressure Stainless Steel Valves Up to 15,000 PSI

BuTech ball check valves prevent reverse flow where leak-tight shutoff is not necessary. Standard materials of construction are 316 stainless steel with 17-4PH poppet for longer life, and 300 series stainless steel spring.

Note: For 316 stainless steel wetted parts, add -316WP to the catalog number.

Cracking pressure: 15 PSI (1 bar) approximate
Operating Temperature Range: -420° to +1200°F (-251° to +648°C)

To order a valve with a cracking pressure other than the standard 15 PSI, add the cracking pressure to the end of the catalog number.

Example: An FPBC8 with 50 PSI cracking pressure would be ordered as FPBC8-50.

Cracking pressures available up to 100 PSI (7 bar)

BuTech o-ring check valves reliably prevent backflow where leak-tight shutoff for liquids or gases is required.

Standard materials of construction are 316 stainless steel with Buna-N o-ring and 300 series stainless steel spring.

Cracking pressure: 15 PSI (1 bar) approximate
