Tyco’s Non-Rising Steam Post Indicator gate valve offers a lightweight ductile-iron body that weighs less than conventional cast-iron valves. It has a fully encapsulated ethylene propylene diene monomer (EPDM) ductile-iron wedge that creates a no-leak fitting and the stem seals are designed with five separate O-rings to provide a lifetime seal. The valve is available with end connections that include flange-by-flange, flange-by-groove and groove-by-groove. Tyco.
