LOW PRESSURE CHECK VALVES

BuTech ball check valves prevent reverse flow where
leak-tight shutoff is not necessary. Standard materials of
A
construction are 316 stainless steel with 17-4PH poppet for
B
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)
