BUTTERFLY VALVES
HIGH PERFORMANCE BUTTERFLY VALVES
VHP SERIES
The VHP Series is a high-performance double-offset butterfly valve available in wafer or lug styles, rated for ANSI Class 150 and 300 in cast steel or stainless steel construction. Its conical angled disc and one-piece A564 Gr.630/PH 17-4 stem deliver high Cv flow with tight shut-off, while interchangeable soft seats (PTFE/RTFE, NBR, EPDM, VITON) or metal seats (A240 Tp 316/304) provide flexibility across a wide range of media. ISO 5211 mounting pads support direct actuation from manual lever or gear operators, as well as pneumatic and electric actuators in sizes 2″ through 24″.

RESILIENT LINED BUTTERFLY VALVES
VRS SERIES
The VRS Series is a resilient-seated butterfly valve available in wafer or lug styles, rated for Class 125/150 service in sizes 2″ through 48″ with body materials including cast iron, ductile iron, aluminum, bronze, or stainless steel. Its one-piece body, hand-polished disc, and cartridge-type seat (available in NBR, EPDM, FKM, PTFE, or silicone) deliver tight shut-off, high Cv, and bi-directional flow, with tool-free seat replacement for easy maintenance. ISO 5211 mounting pads accommodate manual lever, gear, or bare-stem operation, and the valve conforms to API 598 and MSS SP 61 standards, with lug bodies rated for 150 PSI in dead-end service.

VSS SERIES
The VSS Series is a stainless steel (CF8M) resilient-lined butterfly valve available in 2″–48″ wafer and lug configurations rated to ANSI 125/150 for general and industrial service. It features a tight shut-off, one-piece body, blow-out proof stem (A564 Gr.630 / PH 17-4 / 316), bi-directional flow, and a high Cv, with a cartridge-type seat in NBR, EPDM, FKM, PTFE, or silicone that can be changed without special tools. ISO 5211 direct mounting (square shaft 2″–14″, key type 16″–48″) supports lever, gear, or actuator operation, and the valve complies with API 609, API 598, EN 593, BS 5155, ISO 5752/5208/5211, and EN 1092, with shut-off rated at 232 psig (2″–12″) and 188 psig (14″–24″).

TRIPLE OFFSET BUTTERFLY VALVES
VTO SERIES
The VTO Series is a triple-offset butterfly valve available in 3″–48″ sizes with CF8M, WCB, CF8, or WCC body materials and pressure ratings of ANSI 150/300/600/900 for general and industrial service. Its triple-eccentric design and graphite-laminated multi-level seat deliver Class VI shutoff with bi-directional sealing across a -49°F to 1000°F temperature range, plus a 30:1 rangeability and approximate equal-percentage flow characteristic. The valve features a blow-out proof stem, ISO 5211 direct mounting, and is built to API 609, API 598, and ASME B16.5/B16.47/B16.10 standards, with optional rack-and-pinion, scotch yoke, hydraulic, or electric actuation.
