This stainless-steel internal valve model has been designed for use in LPG and NH3 loading and unloading activities for bobtails, transport trucks, nurse tanks, and liquid-storage plants and terminals. The SSA3218F valve is able to be actuated manually, via remote cable or through many types of actuators, which are sold separately. The unit’s cam-type roller openings provide decades of dependable, low-maintenance service life.
Other features and benefits of the SSA3218F valve include:
- Liquid cannot be trapped between the outlet of the valve and downstream shutoff valve, with no need to install a hydrostatic relief valve
- Stainless-steel body, stem, seat and springs that increase service life even when used in the harshest operating environments
- Nitrile seat disc and PTFE stem seals
- Packing that can be easily serviced because the piping does not have to be disconnected in order to remove and repack the stem
- A high-flow design that helps prevent pump cavitation and efficiency loss, resulting in optimized time and cost
- Built-in excess-flow valve and shear studs that meet or exceed industry safety standards
- Maximum allowable working pressure up to 400 psig (27 bar), with a temperature range of -40ºF to 165ºF (-40ºC to 74ºC)
