Overview
V4730C; V4734C; V8730C Gas/Air Servo Regulated Gas Valves & VMU Mixing Units
- Body Pattern: Straight flange Valve
- Opening Time: Dead time maximum: 1 s; First valve – < 1 s
- Materials: Body: Aluminum alloy, die-cast Frequency: 50 Hz; 60 Hz Ambient Temperature Range: 5°F to 140°F (-15°C to +60°C)
- Approvals, CSA: File: Certificate No: 158158-1227192
- Approvals, Others: Gas Appliance Directive: 90.396/EEC, PIN: 0063AT1198, Low Voltage Directive: 73/23/EEC, Electro Magnetic Compatibility Directive: 89/336/EEC
- Maximum Safe Operating Pressure (psi): 0.5 psi (CSA approved), 1.45 psi for 120V)
- Maximum Operating Pressure (mbar): 35 mbar (CSA approved)
- Comments: The minimum load for which the system can be used is 14-17% of the reference load, which equals a minimum pressure differential of 0.2 in. wc (50 Pa) of the 1:1 venturi/servo regulator gas control
- Coil Insulation Solenoid Valves: Class H insulation system VMU Mixing Units
- Has a wide modulation band (14 to 100% of the boiler load).
- Flexible mounting positions of gas control to venturi manifold and venturi manifold to fan.
- Two stainless steel sensing tubes are provided for use with or without manual safety shutoff valve.
- Materials: Housing: Aluminum, Venturi: Statically dissipative statcon PF, Seals: Rubber (NBR)
- Ambient Temperature Range: 32°F to 212°F (0°C to 100°C)
- Approvals, CSA: File: Certificate No: 158158-1227192
- Pipe Connection: Four M5 screws and a rubber O-ring are provided with the venturi to assemble it to the V4730C/V8730C gas valve
- The stainless steel tube provided with the venturi has to be connected between the venturi inlet (connection provided) and the gas valve regulator
- Longer sensing tube for use with manual safety shutoff valve (KTTBA002). Shorter sensing tube for use without manual safety shutoff valve (KTTBA001).
