The optional series BSA is a flat spool. The Spirax Sarco BSA1T globe valve is made of cast iron with a maximum allowable pressure of 16 barg @ 120 ° C and a maximum allowable temperature of 300 ° C. During the test, it has passed the cold water test at a pressure of 24 barg.
Some products and services are only available in certain regions.
Spirax Sarco BSA1T globe valve has zero leakage and high efficiency
Spirax Sarco bellows-sealed globe valves provide a new environmentally demanding solution for on / off valves. The use of a bellows seal design ensures that stem leakage is eliminated and meets the world's most stringent sealing standards. This is essential for ensuring plant safety valves, saving energy and maintaining a clean working environment.
Complies with European Pressure Equipment Directive 97/23 / EC.
Ergonomically designed handwheel.
Rugged non-lifting handwheel firmware.
The corrugated pipe is imitation twisted and does not come into contact with fluids and has a long corrosion-resistant life.
Titanium reinforced stainless steel double bellows.
100% tightness test.
Standard configuration: BSA2T globe valve with stainless steel spool, seat and stem.
Product Features of Spirax Sarco BSA1T Globe Valve
Long life: The structural design of the Spirax Sarco BSA2T globe valve bellows seal will not cause any failure during operation, and the fatigue life of the bellows meets the latest international standards. Should the bellows fail, the packing seal on the valve stem provides a secondary seal to prevent leakage.
Maintenance-free: The bellows sealing structure not only eliminates leakage, but also requires no maintenance. If it is necessary to replace the internal parts, it is also very simple and fast. All gaskets are free of asbestos.
Rugged: This product is immune to vibration and can operate over a wide range of pressures and temperatures.
Throttle spool: The latest BSA2T globe valve model uses a throttle spool instead of a traditional flat spool. It can manually control the pressure and flow in the system manually, and can also replace the bypass valve for rough control. All BSA-T globe valves use double bellows to extend the life of the product. At the same time, the bonnet is provided with a lock nut, which can fix the valve opening in a certain position.
Spirax Sarco BSA1T globe valve process application
Bellows sealed BSA2T globe valve can be widely used in various industrial fluids, such as: steam, air, hot kerosene, hot water and cold water systems. Caliber from DN15 to DN250: pressure rating to and CLASS800. Flange, thread and socket welding are available, suitable for most process applications.
