 The Emech 2 port valve utilises ceramic shear action disc technology to provide tight shut-off, high pressure differential capability and long life integrity. Combined with the Emech electronic actuator, high speed stand alone closed loop control is possible. The Emech 2 port valve utilises ceramic shear action discs as the dynamic seal. The extremely hard nature of ceramic produces outstanding resistance to wear and cavitation damage compared with conventional elastomer and plastic seated valves, minimises seal replacement and plant downtime. ›› Download pdf Product Specifications ›› Download dxf Product Drawings Valve Features › ISO 5211, 5210 actuator flange mounting › Constructed of either 316 stainless steel › Ceramic discs durable, corrosion resistant › NPT / BSP / Butt weld / socket / ANSI flanged › Elastomer seal options › Top entry allows inline access to internal valve parts Size range › 20, 25, 40 and 50mm ( ¾", 1", 1½" and 2" ) Rated pressure › 20 bar (290 psi) Maximum dynamic pressure drop › 9 bar (130 psi) Manual handle option › lockable open and closed Liquid, gas, and steam capable ›Screwed ANSI cl. 800 version ›Integral 1/2" sensor ports are available for fitting of ›transducers Electronic Control The Emech 2 port valve can be fitted with the Emech electronic actuator to provide modulating control. Closed loop control can be achieved by connection of appropriate sensors to the actuator.eg. temperature flow, or pressure transducers.
