Each valve hydrostatically tested on both sides to 225 PSI.

Dual stem seal is between disc and seat spherical hubs additional seal from seal O-ring.

Oil impregnated bronze bushings provide maximum stem support while accepting side loading to minimize torque for peak operator performance.

Two piece blowout proof stem design allows field replacement of seats.

Streamlined disc design reduces pressure drop and minimizes turbulence.

Resilient seat design eliminates the need for flange gaskets.

Long neck design allows ample clearance for insulation.

All lug bodies are threaded. Drilled holes are optional.
