148B5609 Danfoss Stop/check valve, SCA-X 40 A, Angle 1 1/2" BW

SCA-X are check and stop valves with built-in stop valve function. SCA-X valves are available in angleway versions. The valves are designed to open at very low differential pressures, allow favourable flow conditions and are easy to disassemble for inspection and service. SCA-X valves are equipped with vented cap and have internal backseating enabling the spindle seal to be replaced whilst the valve is still under pressure. Laser cut V-ports provide excellent opening characteristics (SCA-X 50-125). The valve cone has a built-in flexibility to ensure a precise and tight closing towards the valve seat. A well balanced dampening effect between the piston and the cylinder gives an optimal protection during low loads and against pulsations.

Features:

• Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO2), Propane, Butane, Iso-Butane and Ethane.
• Modular Concept: – Each valve housing is available with several different connection types and sizes. – Possible to convert SCA-X or CHV-X to any other product in the FlexlineTM SVL family (Hand operated regulating valve, shut-off valve or strainer) just by replacing the complete top part. 
• Fast and easy valve overhaul service. It is easy to replace the top part and no welding is needed.
• Designed to open at a very low differential pressure of 0.04 bar /0.58 psig.
• Designed with a built-in damping chamber preventing valve flutter in case of low refrigerant velocity and/or low density.
• Each valve is clearly marked with type, size and performance range. 
• Easy to disassemble for inspection and service.
• Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure. 
• Optimal flow characteristics ensuring quick opening to the fully open position.
• Protection against pulsation by built-in damping facility.
• Housing and bonnet material is low temperature steel according to requirements of the Pressure Equipment Directive and other international classification authorities.
• Equipped with Stainless steel bolts. 
• Max. working pressure: 52 bar g / 754 psig 
• Temperature range: -60 – 150 °C / -76 – 302 °F
