Butterfly Valves
Butterfly Valves Lock Lever Actuator
Butterfly Valves Lock Lever Actuator is a group of 15 IMPA-coded items (codes 752201–752247) under Butterfly Valves in the Valves & Cocks section (IMPA 75). All of them are priced per piece. The list runs through imperial sizes from 1-1/2" to 8".
Buying guide
Butterfly valves with a lock lever are quarter-turn valves: a disc on a shaft swings across the bore and a notched lever holds it open, shut or at a set position. The group covers wafer-type bodies, clamped between two pipe flanges, and semi-lugged bodies, in inch sizes.
They are the compact isolation valve of sea-water, fresh-water and ballast branch lines where a gear box is not needed. The engineer raises them as renewals when the seat liner wears and the valve passes, or when a lever or shaft seizes.
How to specify it
Give the size, the body type (wafer or semi-lugged), the flange standard and class the valve must fit between (JIS 5K/10K, DIN PN10/16 or ANSI 150), the body, disc and seat materials, and the service fluid. A wafer valve is located by the flange bolts, so the flange drilling it is made for matters as much as the size.
Quote the face-to-face length of the valve being replaced. ISO 5752 standardises face-to-face dimensions of metallic valves with flanged or wafer ends so that a valve from a different maker fits without pipe modifications; name the series given on the old valve’s data so the offer matches it.[1]
Questions buyers ask
- Wafer or lugged — which do I need?
- Match what is fitted. A wafer body is clamped between the two flanges by the flange bolts; a semi-lugged body has bolt lugs cast on. The catalogue lists them as separate items.
- Will a butterfly valve from another maker fit the same gap?
- Only if it is built to the same face-to-face series. ISO 5752 exists for that interchangeability, so state the series and the old valve’s length on the requisition.
