Features:
- BODY
Conforming to AWWA C517 wall thickness, the Eccentric plug valve body casting is in ASTM A-536- Grade 65-45-12 Ductile Iron using high-pressure moulding techniques. - SEAT
The Eccentric plug valve incorporates as standard, on DN80 and larger, a 1/8” thick welded 99% nickel seat for corrosion and erosion resistance, specifically profiled for low torque and extended seat life. - STEM SEAL
High integrity sealing is achieved by combining the advantages of a resilient and abrasion-resistant V-ring seal. From vacuum to high pressure, the self-adjusting sealing system (per AWWA C504) gives positive, trouble-free service and is retained independently of the plug stem or external torque device, thereby eliminating periodic maintenance. - BEARINGS
The plug rotates in permanently lubricated 316 grade stainless steel bearings, located in the body and bonnet, along with upper and lower PTFE thrust washers, which ensure consistently low operating torque. - PLUG
Supported on integral trunnions, the plug is totally encapsulated with an elastomer that is moulded on to the casting, providing tight shut off even under vacuum conditions. High-integrity corrosion-free sealing is achieved by a variety of abrasion resistant elastomers, which protect the plug right up to the trunnions. When assembled, the light compression of the elastomers onto PTFE thrust washers prevents entry of abrasive materials into the bearings. - BONNET SEAL
Superior “O” ring sealing with metal/metal contact means lower bolting stresses compared with compression gaskets. - FLOW
The port design (round on DN80–300 and rectangular on DN350 and larger) with streamlined internal contours gives the highest industry capacity straight through flow in the full open position, reducing turbulence and pressure drop and the effect of erosive media. Handling of sludges and slurries is therefore enhanced. - INTERCHANGEABLE
Because of the common face-to-face dimension (BS5163) with Resilient Seated Gate Valves in sizes DN80 –300, fitting the Eccentric plug valve into existing systems is accomplished without pipeline modifications. - TRAVEL STOPS
Adjustable open and closed travel stops are fitted as standard
on both wrench and gear operated Eccentric plug valves.
