Spirax Sarco UK ball high standards of design and manufacturing, to provide reliable and low maintenance shut tight. Wide product range, a variety of sizes, materials and body design conditions for a variety of applications. 1/4 turn switch compact design, easy operation and maintenance. ISO mounting interface, installation is quick and easy and automatic controller adaptation. Torque is small, configurable small pneumatic actuators. High throughput, low pressure drop. Body corrosion, ensuring long life. Spirax Sarco M10S valve for steam applications Spirax Sarco steam valve systems and related equipment has eighty years of experience and knowledge. In the steam system applications, and sometimes must be isolated for steam piping or equipment, whether manual or automatic control, Spirax Sarco ball valves are able to provide a safe, predictable, a reliable isolation, because they are designed for steam systems application and design. Steam system does not allow the slightest careless demanding, requiring the best design. After years of research and development, manufacturing equipment, and constantly updated experience in the successful application of a number of important occasions, making Spirax Sarco ball valves meet this requirement. ? All Spirax Sarco products are fully meet the European Pressure Equipment Directive 97/23 / EC. ? No leaks - thanks to a single seat / seal surface design. ? High flow capacity, low pressure drop, low energy loss. ? Low operating torque - sticky or drift phenomenon does not occur when high-pressure application operations. ? Automatic compensation of seal wear - Belleville spring washers. ? Facilitates automatic control - some models with ISO mounting as standard. ? Seat and seal materials to choose PTFE, R-PTFE, PEEK, PDR0.8. ? ISO9001 / 2000 quality system certification - Material Tracking and related certification. ? Spirax Sarco to provide technical support and services worldwide. Spirax Sarco ball float concept floating ball with soft seat design approach, to ensure that the ball valve to achieve ANSI VI level seal level. Only the use of appropriate high-quality products, in order to make safe and reliable operation of the steam system. Resilient seat materials at high or low pressures can guarantee tight shut-off, and can reduce wear and valve operating torque. Some models feature a one-piece seat / body gasket, clean steam cavity filler models are also available. All ball valves for steam applications are specifically designed. PTFE material with a low friction, durable, low thermal resistance, good chemical stability. Recommended for saturated vapor pressure of 10bar g. The steam sealing material. DuPont developed specifically for Spirax Sarco sealing material with high temperature adaptation (260 ℃), low coefficient of friction. Recommended for saturated steam pressure 17.5bar g. Polyether ether ketone (PEEK) has a tough material, high temperature, thermoplastic good - with high tensile and shear strength, excellent creep resistance, fatigue resistance, and resistance to chemical corrosion properties. Recommended for saturated vapor pressure of 39bar g. R-PTFE (25% glass-filled) with excellent resistance to compression and heat resistance reduces wear at high loads. Especially recommended for clean steam applications. PTFE glass filled PTFE (R-PTFE) PDR 0.8 lockable handle automatic control valve Spirax Sarco recommend using ISO mounting for automatic control. Provides electric actuator 1/4 circle (BVEA200 series) and single / double acting pneumatic actuators (BVA200 series), with full coupling limit switches and gearbox for manual override. These accessories can be assembled to form a single compact component provides. For more information, please refer to the automatic control of product samples.
