Effective solar heat depends on the solar and water temperature and the start and stop differentials, then SolarTouch® Controller will rotate the positive 3-way valve and turn on the solar booster pump or increase the RPM''s if an IntelliFlo® or IntelliPro® Pump is present. This allows the water to flow to the solar collectors.
These safety relief valves are used to control pressure in the primary circuits of solar heating systems. When the calibrated pressure is reached, the valve opens to release the fluid into the atmosphere and prevents the pressure in the system from reaching levels that might damage the solar collectors and equipment. These particular series of

In a direct spring loaded safety valve the closing force or spring force is applied by a helical spring which is compressed by an adjusting screw. The spring force is transferred via the spindle
Safety valves must be accessible on the heat generator or built into the supply pipe in its immediate proximity, without a barrier between the heat generator and the safety valve.
In a direct spring loaded safety valve the closing force or spring force is applied by a helical spring which is compressed by an adjusting screw. The spring force is transferred via the spindle onto the disc. The disc seals against the nozzle as long as the spring force is larger than the force created by the pressure at the inlet of the valve.
The spring force is transferred via the spindle onto the disc. The disc seals against the nozzle as long as the spring force is larger than the force created by the pressure at the inlet of the valve. The figure shows the enlarged nozzle and disc area of a safe-ty valve with the forces acting on the disc.
The LESER Pilot Operated Safety Valve (POSV) is controlled by process medium. To achieve this, the sys-tem pressure is applied to the pilot valve (= control component for the main valve) via the pressure pickup. The pilot valve then uses the dome above the main valve piston to control the opening and closing of the main valve.
PILOT-OPERATED SAFETY VALVES Pilot-operated safety valves limit the pressure in the system by compensating for the overpressure by opening the main valve. They are self-medium controlled and, as with all medium-loaded safety valves, the same pressures act on both sides of the sealing disc.
A safe-ty valve is designed to open and relieve excess pressure from vessels or equipment and to reclose and prevent the further release of fluid after normal conditions have been restored. A safety valve is a safety device and in many cases the last line of defence.
DGH valves may be used. DSV...DGF valves can be used for solar systems with higher temperatures and evaporation. In cold water systems where evaporation can be excluded, DSV F*) series valves can be used. The DSV ..DGF series valves are to be used when there is a risk of refrigerant gas entry.
If more than one safety valve is used in parallel, the smaller must have a blow-of capacity of at least 40% of the total. Safety valves must be designed so that the maximum permissible operating pressure that can occur in the heating system, or in a part thereof, may be secured.
