Jerguson 70BL and 70XL Ballcheck Valves for Armored Glass Level Gages

Jerguson 70BL and 70XL safety ballcheck valves are rugged, lightweight valves designed for use with Jerguson flat glass gages, instrument piping or other applications requiring such valves. In case of gage glass breakage, all 70BL series valves are equipped with a stainless steel ballcheck upstream from the seat that instantaneously shuts off flow of medium being gaged.

The 70BL is a safety ballcheck valve. The 70XL is an instrument valve without the ballcheck mechanism. Both valves come in straight or offset designs with your choice of NPTF or union gage connections.
