Spirax Sarco UK Spirax sarco bellows valve, zero leakage, high efficiency Spirax Sarco bellows sealed globe valves for on / off valve provides a new class environmental needs solutions. Bellows seal design forms can be cut to ensure the elimination stem leakage, can meet the world's most stringent standards of sealing. This is to ensure the safety valve factory, saving energy and maintaining a clean work environment is critical. We guarantee that under normal circumstances there is no leakage at any valve stem. Spirax Sarco UK bellows valve Model: BSA1 BSA1T BSA2 BSA2T BSA3 BSA3T BSA6T BSA64T A3S other products. For more products, please contact us about the flow parameters. Product Features: Advantages: 1. No leakage losses, energy and protect the environment. 2. Simple operation. 3 long life. 4. No protection. 5 full compliance with the European Pressure Equipment Directive. 5 Spirax Sarco provides global technical support. Long life: bellows seal design will not have any trouble at the time of operation, the fatigue life of the bellows to meet the latest international standards. Unfortunately, if the bellows failure, the valve stem packing seal provides a secondary seal to prevent leakage. Maintenance-free: bellows seal structure not only eliminate the leakage, and no maintenance. To replace the internal parts, is also very simple, fast, and all the gaskets are asbestos-free. Durable: This product is not affected by vibration, can work in a wide range of pressure and temperature range. Throttle core: the latest BSA-T model uses a throttle valve core instead of the traditional flat, you can manually on the pressure and flow within the system a little fine-controlled bypass valve can also replace a rough control. All BSA-T model shutoff valves are double bellows, to extend the life of the product. Meanwhile bonnet with a lock nut on the valve opening can be fixed in one position. Application Process: bellows sealed globe valve can be widely applied to various industrial fluids, such as: the steam-air heat kerosene hot and cold water systems. Caliber from DN15 to DN250: pressure levels to PN40.ANSE300 and CLASS800. Available Flanged, Threaded and socket weld connections, etc., applicable to most process applications.
