Back check valves allow flow in only one direction and are normally closed. They are installed in liquid filling connections on stationary storage tanks, bobtail delivery trucks and liquid transfer lines.
G200 Series – back check valves are specifically intended for heavy-duty in-line service at the bulk plant’s transfer area. The valves are suitable for LP-Gas or Anhydrous Ammonia (NH3) service.
Flow moves the spring loaded poppet to the open position as soon as pressure differential is created. When flow stops, the poppet closes. A soft seat construction gives tight shutoff so that piping can be blown down for maintenance.
The G200 Series is built to stay on the job with all internal parts of plated steel or stainless steel.
