Jerguson® Series 140™ Safety Ballcheck Valves
Jerguson No. 140 Series Valves provide long trouble-free service at economical cost. Their design incorporates such quality features as stainless steel stems and ballchecks. A comprehensive selection of connections provides the versatility required to conform to most piping requirements. Optional features permit a high degree of customization to meet very specific demands.
No. 140 Series Valves
The series consists of the following valves:
No. 143 – straight pattern with non-union gage connection
No. 144 – straight pattern with union gage connection
No. 146 – offset pattern with non-union gage connection
No. 147 – offset pattern with union gage connection
Safety Shut-off: All No. 140 Series Valves are equipped with stainless steel ballchecks upstream from the seats which instantaneously shut-off flow of medium being gaged in case of gage breakage. The ball may be omitted on request.
Bonnet: The bonnet on all No. 140 Series Valves screws directly onto the outside of the forged body. The inner area bears on the packing gland.
Union Tank Connection: Series 140 Valves are equipped with union tank connections which permit simple installation and easy access to the ballcheck.
Union Gage Connection: No. 144 and No. 147 are furnished with a union gage connection which allows a top and bottom connection gage to be turned to any desired angle for convenient visibility. It also makes possible removal of the gage without removing the valves or draining the liquid from the vessel – a feature which saves time when the gages must be cleaned or maintained.
Offset Pattern: No. 146 and No. 147 valve bodies are designed so that the gage connections are offset 7/8″ from the centerline of the vessel connection. By removing the plug, the interior of top and bottom connected gage may also be swabbed without disassembly.
