KI Series (BVKI Wafer / BLKI Lug / BFKI Double Flange) — Soft Seated Butterfly Valve
Ghibson's most widely specified soft-seated butterfly valve, designed for the full range of industrial and marine applications including water treatment, HVAC, chemical service, seawater, pulp and paper, power plant cooling, and vacuum service.
KA Series (BVKA Wafer / BLKA Lug) — Higher Pressure Soft Seated Butterfly Valve
Ghibson's industrial and marine soft-seated butterfly valve rated for higher working pressures than the KI series.
KX Series (BVKX Wafer / BLKX Lug) — High Pressure Compact Soft Seated Butterfly Valve
Ghibson's highest-pressure soft-seated butterfly valve in the resilient seat range, designed specifically for demanding marine, petrochemical, and vacuum service applications.
PD Series (BVPD Wafer / BLPD Lug) — Low Pressure Soft Seated Butterfly Valve for Powder and Bulk Service
Ghibson's soft-seated butterfly valve designed specifically for low-pressure service including powder conveyance, dry bulk handling, and fluid systems where a low-profile, economical valve is required.
TT Series — PTFE Seated Butterfly Valve for Chemical and Heavy Duty Service
Ghibson's PTFE-seated butterfly valve, engineered for aggressive chemical, pharmaceutical, and heavy-duty industrial applications requiring resistance to corrosive media. The PTFE lining extends to envelop the shaft, and the double packing mechanism — an FEP-coated FKM O-ring combined with a PTFE C-ring — provides zero leakage along the shaft.
HD Series (BVHD Wafer / BLHD Lug) — High Performance Double Eccentric Butterfly Valve
Ghibson's high-performance butterfly valve, designed for demanding applications where critical sealing performance, elevated pressures, high cycle life, and fire-safe integrity are required.
N500S / N501S Series — Resilient Seated Butterfly Valve (ANSI/North American)
Ghibson's ANSI-rated resilient seated butterfly valve range for water, utilities, HVAC, and general industrial service to North American flange standards. Available from 1½" to 24" (DN 40 to DN 600) in wafer (N500S) and lug (N501S) body styles. Pressure rating 250 psi (1½"–20") and 150 psi (24"), conforming to ANSI B16.1 and ANSI B16.5 flange standards. NSF/ANSI 61 and NSF 372 certified for potable water service.
