Single Chamber Control Valve - Full Port with Mechanical Check - M400, M1400

Series M400, M1400 are full port, single chamber basic valves that incorporate a two-piece disc and diaphragm assembly. This assembly is the only moving part within the valve allowing it to open, close, or modulate 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

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