Dual Chamber Control Valve - Reduced Port with Mechanical Check - M6518, M61518

Series M6518, M61518 are reduced port, dual chamber basic valves that incorporate a two-piece telescoping disc and diaphragm assembly. This assembly is the only moving part within the valve, allowing it to open or close as commanded by the pilot control system. The lower portion of this two-piece assembly is a mechanical check feature, which acts independent of diaphragm position or pilot control system, and provides immediate check action when flow ceases.

Features

• Body and cover are constructed of strong and durable ductile iron (ASTM A536)
• Two-piece assembly opens, closes, or modulates as commanded by the Pilot Control system
• Simplified and efficient design is easy and economical to maintain
• Mechanical check feature provides immediate check action when flow ceases.
