OverviewThis document provides detailed specifications and applications for valve couplings used with PRISMA pneumatic actuators. It includes information on various types of brackets and drive adapters designed to connect actuators to different types of valves, such as ball, butterfly, and plug valves.
Brackets- A Type Bracket: Used for ball valves with cylindrical bodies without mounting pads. Made from Rilsan-coated steel.
- B Type Bracket: Suitable for ISO-5211 ball and butterfly valves, available for valves with or without ISO-5211 topwork. Made from AISI-304 stainless steel.
- C Type Bracket: Designed for 3-piece ball valves without ISO-5211 topwork. Made from AISI-304 stainless steel.
- D Type Bracket: Similar to C Type, for 3-piece ball valves without ISO-5211 topwork. Made from AISI-304 stainless steel.
- J Type Bracket: For ISO-5211 ball and butterfly valves, also available for non-ISO 5211 top flange valves. Made from AISI-304 stainless steel.
- M Type Bracket: For ball or butterfly valves with ISO-5211 F05-F07-F10 topwork. Made from polyamide.
- N Type Bracket: For ISO-5211 ball and butterfly valves. Made from AISI-304 stainless steel.
Drive Adapters- CP Type Drive Adapter: For ball and butterfly valves with squared shafts according to ISO-5211. Available in AISI-316 stainless steel and zinc-coated steel.
- DD Type Drive Adapter: For ball and butterfly valves with double D shafts according to ISO-5211. Available in AISI-316 stainless steel and zinc-coated steel.
- Zinc-Coated Steel Drive Adapters: Various types for fitting to valve shafts of different internal shapes.
- Stainless Steel Drive Adapters: Made from AISI-303 stainless steel, designed for fitting to valve shafts of different internal shapes.
