The Mach 1 Marathon is designed for reliable performance in high cycle on-off or modulating services. Fugitive emission containment is often equal to more expensive severe or toxic service valves.
Main feartures:
Viton1 O-rings
Full pressure containment stem seal.Also protects thrust collar from atmospheric corrosion. Kalrez1 and other elastomers are available. PTFE backup rings help prevent extrusion of Viton O-rings under pressure.
Integral Thrust Collar/Alloy Diaphragm
Self-sealing, dynamic bellows-like diaphragm moves with plug adjustment to eliminate potential leak path.Hastelloy2 (or optional materials)diaphragm welded to alloy thrust collar.
Unique Stem Sealing Design
A pair of Viton O-rings prevents stem leakage while containing line pressure. Fugitive emission containment is often equal to more expensive severe.
