Features
SVA Stop Valves are available in angleway and straightway versions and with Standard neck (SVA-S) and Long neck (SVA-L)
The stop valves are designed to meet all industrial refrigeration application require-ments and are designed to give favourableflow characteristics and are easy to dismantleand repair when necessary.
The valve cone is designed to ensure perfect closing and withstand a high system pulsation and vibration, which can be present specifi-cally in the discharge line.
Stainless steel bolts.Maximum allowable working pressure and temperature range: Temperature: –50°C/+150°C (–58°F/+302°F Max working pressure: SVA-S/L (DN 15-65) 52 bar (754 psi) within the temperature range –50°C/+50°C (–58°F/+122°F) SVA-S/L (DN 80-200) 50 bar (725 psi) within the temperature range –50°C/+50°C (–58°F/+122°F) Please refer to the pressure and temperature curve at page 2 for maximum working pressure within the temperature range –50°C to +150°C (–58°F to +302°F).

y FPT Female Pipe Thread, NPT (ANSI/ASME B 1.20.1),
DN 15 - 32 (½ - 1¼ in.)HousingMade of special, cold resistant steel.Valve coneThe valve cone can be turned on the spindle, thus there will be no friction between the cone and the seat when the valve is opened and closed and the special design will avoid cone spin due to pulsation and vibration when the valve is in open position. A teflon tightening ring provides perfect sealing with minimum closing force.SpindleMade of polished stainless steel, ideal for leap seal sealing.Packing glandThe low temperature packing gland ensures a perfect tightness in the range: –50/+150°C (–58/+302°F). The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice into the packing gland.
Pressure Equipment Directive (PED)SVA valves are approved according to the European standard specified in the Pressure Equipment Directive and are CE marked.For further details / restrictions - see Installation Instruction.InstallationIt is recommended that the valves be installed in the direction of flow indicated by the arrow on the valve body. The valve can be installed in the opposite direction but this slightly reduces the kv-value (Cv-value).The valve is designed to withstand high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion.For further information refer to installation instructions for SVA.
Example of Marking Ring
SVA
Nominal bore DN≤ 25 mm (1 in.) DN32-80 mm (1¼ - 3 in.) DN100 - 200 mm (4-8 in.)
y Pressure range The valves are designed for max. working pressure 52 bar g (754 psi g).
Technical data y Refrigerants Applicable to all common refrigerants inclu-ding flammable hydrocarbons and all non-corrosive gases/liquids. For further information please see installation instruction for SVA.
Important!Where products need to be certified according to specific certification societies or where higher pressures are required, the relevant information should be included at the time of order.
Please note that the type codes only serve to identify the valves, some of which may not form part of the standard product range. For further information please contact your local Danfoss Sales Company.
