VCZ-4104AMBD KMC Kreuter Pneumatic Zone Control Valve

KMC VCZ-4104AMBD 1″ Pneumatic Zone Control Valve – 7.0 Cv, Fail-Open The KMC VCZ-4104AMBD is a rugged OEM pneumatic globe zone valve designed to regulate hot or chilled water flow in HVAC applications. With a 1-inch two-way female NPT body and a high-flow coefficient (Cv 7.0), it operates on a pneumatic actuator pressure range of 3-8 PSI and is normally open (fail-open), ensuring safe operation in cases of loss of air supply. Key Features & Benefits High flow capability: Cv 7.0, ideal for moderate piping applications. Pneumatic actuator range: 3-8 PSI for precision control. Normally Open (Fail-Open) design for default safe position. Durable materials: brass trim, neoprene diaphragm, glass-filled nylon actuator housing ensure long life and corrosion resistance. Compact size (7×6×5 in) and light weight (~3 lbs) facilitate installation even in tight spaces.
