Description
Mansfield & Green Type SNJ Series diaphragm seals are flow thru type seals designed for pressure measurement applications involving jacketed pipelines where heated process fluids are used.
The SNJ seals have slip-on flanges for ease of installation and alignment. Socket weld jacket connections are included for field installation.
The SMJ model is similar to the SNJ seals except these seals do not include flanges. The SMJ seal is butt welded directly into the customer?s jacketed pipeline. Type SMJ and SNJ seals are continuous duty and feature a welded diaphragm seal design with the diaphragm welded directly onto the instrument housing.
The interior of the diaphragm top is contoured to fit the movement of the diaphragm at maximum allowable deflection. This minimizes distortion. A filling screw is provided standard.
