Description

Sell TUV.SV-SFA15-SFV20-25 Danfoss Safety relief valves Design
Connections
Available with the following connections: Outside pipe thread T (ISO 228/1) Welding fittings (DIN 2448)
Housing
Made of special steel approved for low temperature operation. Spindle and seat are made of stainless steel, to ensure precise operation even during extraordinary conditions. The gasket of the valve cone is made of a special cloroprene (neoprene) compound.
Installation
To ensure exact operation of the safety relief valve it should be installed with the spring housing upwards. If the valve is mounted as an
internal safety relief valve without any demand for exact opening pressure, the valve may be fitted with the spring housing in other positions. When the valve is mounted, it is important to avoid the influence of static, dynamic and thermal stress.
A very precise technique has been applied for the production of the seal. However, this seal can still be damaged, if dirt is blown from the pipe system into the valve. It is recommended that safety relief valves exhaust into the open air with a U-pipe filled with oil on the discharge branch, to prevent dirt from penetrating into the valve. It is also recommended that the valves be installed in pairs in conjunction with the double stop valve type DSV. For further information please see the DSV data sheet.
Re-calibration/servicing
In certain countries the authorities demand that the valves are checked at least once a year (see local rules).
Control/Identification
After adjustment of the set pressure at Danfoss,the valves are sealed. For that reason Danfoss can only guarantee correct operation, as long as the seal remains unbroken. All valves are provided with a metal plate with
the following information:
- Flow diameter
- Set pressure
- Date of production
- Production number
- Type approved code.
