Butterfly Valve, sizes 2″ through 48″ ANSI 150, 2″-48″ ANSI 300, 3″-24″ Suitable for high temperature, high pressure, fire, corrosion and other harsh conditions of use and applied to use in petroleum, natural gas, chemical, refining, energy and power, ultra-low temperature for the process off site and the role of regulating valve.
Precision cast bodies in virtually any alloy allow customers to utilize proper materials for virtually any application. Castings conform to all applicable ASME codes. Certified independent testing can be performed when requested or required such as RT and PT. Bodies are available in Wafer, Lug, Double Flanges .
FMC is designed to have minimal deflection and movement under pressure which reduces torque and improves cycle life. The discs tapered edge and offset shaft journal generates a “cram” motion allowing for a release from the seat within the first few degrees of opening.
Our hardened 17-4 one piece design provides shaft strength and integrity under the most severe conditions. Other shaft materials are available depending upon application.
OUR seat is machined to lock between the body and retention ring but is allowed to move under pressure. This allows us to utilize solid seats giving maximum disc edge coverage, high cycle life and very low torque without the requirement for rubber O-ring energizers or metal back up support.
Our recessed gland packing eliminates the requirement for mounting kit and reduces overall package height. Our cup and cone design gland flange and packing compression guide allows an even compression of packing even if field adjustments are made incorrectly.
Bonnet to flange clearance is a minimum of 2” allowing for piping insulation on all sizes of valves.
Seat Retention Ring
Our highly engineered retainer plate assures customer of proper seat stability and allows for full rated bi-directional, dead end service. The HP series seat retention ring conforms to the latest revisions of API 609 accommodating spiral wound gasket sealing elements to fall outside the bolting area.
Allows for direct mounting of all types of actuation. Standard drilling conforms to Kv industrial standards. ISO drilling is also available upon request.
Multi layered “cup and cone” PTFE packing allows for even compression against shaft and shaft journal area providing a positive seal even under high cycles. Multi layered graphite packing is available for metal seated and fire safe valves.
Blowout Proof Shaft Retention
Engineered to be one of the safest valves in the market our shaft retention system meets API requirements. Shaft retention system allows the gland flange and follower to slide up and down a machined recessed portion of the shaft. If a shaft were to shear our system prevents hydraulic force from projecting the shaft keeping it safely retained above the packing.
