Product Design Benefits
1. Body
Valve body casting uses pressure moulding techniques for consistent quality and precision. Flange diameter and thickness conform to ANSI B 16.1 Class 125. Flange drillings PN10, PN16, ANSI
2. Seat
The Multiport valve employs a corrosion and abrasion resistant epoxy seat on all sizes
3. Stem Seal
Multiple self-adjusting “U” cup seals are used to prevent stem leakage and provide years of trouble free service
4. Bearings
The plug rotates in oil impregnated sintered 316 grade stainless steel bearings located in both the body and bonnet
5. Plug
supported on integral trunnions, the solid ductile iron tapered plug is faced with any of a variety of elastomers that are vulcanized in place and ground to size. Plug position and shut off is controlled by use of adjustment gland attached to the plug shaft
6. Bonnet Seal
Superior ‘O’ ring sealing with metal/metal contact means lower stresses compared to traditional compression gaskets
7. Flow
The wide port design with streamlined internal contours allows for a high capacity flow in the full open position reducing turbulence and pressure drop through the valve
8. Position Indication
Active port indication is standard on all wrench operated and gear operated millcentric Multiport valves
