GVG6013 electric valves Introduction: GVG6013 series of electric valve for control of central air conditioning system, heating system pipe open or closed, to control room temperature purposes. Control valve consists of a one-way hysteresis synchronous motor, spring return. When the valve does not work in a normally closed state, when the need to work, provided by a thermostat valve opening signal pneumatic butterfly quote, electric valve connected to AC power and action, open the valve, chilled water or hot water into the fan coil Anhui pneumatic valve for room air-conditioning or heating; when the temperature reaches the thermostat setting, the thermostat so that electric power pneumatic butterfly valve principle, the return spring to the valve closed, thus cutting off the flow of water into the fan coil. By closing and opening the valve pneumatic valve, so room temperature is always maintained at the thermostat setting temperature range. Leakage: Metal seat: valve rated capacity of less than 0.01%, in line with ANSI B16.104-1976IV class soft seat: valve rated capacity of less than 10, in line with ANSI B16.104-1976IV level hysteresis: with a locator: Less than 1% of the whole trip, without locator: less than 3% of total travel (LHA1 type less than 5% of the whole trip) Basic error: With locator: less than a full stroke of ± 1%, without locator: less than full stroke of ± 5% NOTE: The standard V-type PTFE packing adjustable range: 50: 1 (0.25≤Cv≤14) or 30: 1 (CV≤0.16) pneumatic valve Quote | Tianchang instrument linked instrument (Certified ) | pneumatic valve provided by the United Instrument Sales Co., Ltd.
