Prescor Safety Valves: omplete Range for the Safety of Your System If you are looking for reliable safety valves, you need look no further than Flamco's Prescor range. The best protection for all sealed heating and chilled systems from overpressure. The Prescor valves are suitable for systems with a capacity of up to 580 kw at.0 bar. Systems with greater capacity will need the heavy-duty Prescor S. The enefits of Prescor High-quality materials and construction guarantee reliable function. If there is a rapid build-up of pressure, the valve will 'pop' open. The pressure can then be discharged quickly. E conformity mark (PE 97/2/E). The opening pressure of all valves is individually tested. ap of high-impact plastic. nti-ageing spring steel prevents the set pressure from drifting. Robust brass housing. The diaphragm prevents moisture and dirt from getting into the moving parts of the safety valve during blowing off. Valve seal of high-quality rubber, heat-resistant to 140 º. The hardness of the rubber is adapted to the set pressure of the valve. These properties mean that the valve will not stick to the valve seat. PRESOR ll Prescor safety valves are set to the specified opening pressure during manufacture. This setting cannot be adjusted. It is important to check the requirements for the Prescor valve in advance. When choosing a Prescor safety valve, the capacity shown on the safety valve must exceed the nominal boiler capacity. Mount on the boiler, or as close as possible to it, in the supply line. Never fit a stopcock between the boiler and the valve. 92 Product overview 201 We reserve the right to change designs and technical specifications of our products.

SFETY VLVES Prescor safety valves have a special shape, which not only achieves a perfect seal, but also a large blow off capacity. The valve seal is made of high quality rubber, which is heat resistant to 140, and where the hardness of the rubber adjusts to the set pressure of the safety valve. In this way, the valve cannot stick to the seat. ll valves are tested before they leave our facility and are available for heating and cooling installations, as well as for protection of various hot water storage appliances.

The Solution for Hydraulic Imbalance in entral Heating Installations Increasingly, heating installations are fitted with several boilers. s a result, individual boilers can be switched on or off, depending on the heating requirements. In addition, there are often multiple sub-systems fitted with individual pumps. With these systems, there is a chance of hydraulic imbalance, which will lead to poor heat transfer, overloading of pumps and a system that is difficult to stabilise. Using a Flexalance hydraulic balancer prevents this problem and improves the efficiency of the system. one-shaped air chamber. rea where the air is collected. Supply connections. Steel body. age with PLL rings for air (top) and dirt (bottom) separation. rainage tap for removing pollutions that are heavier than water. Return connections. rea where the dirt particles are collected. FLEXLNE PLUS How a Hydraulic alancer Works y fitting a Flexalance balance vessel, the primary and secondary circuits are connected and a balance is maintained between the various flow speeds. The flow in the primary and secondary circuits stays independent in all situations. The flows in both sub-circuits are not influenced in any way.

ccessories for Heating and ooling Installations Flexalance Hydraulic alancer enefits No more overloaded pumps. More accurate regulation of the system is possible. onsiderably improved warmth transference. Higher output by the system. Two Extra Flexalance Functions Flexalance hydraulic balancers must be placed between the primary and secondary circuits to balance out both circuits. This is also the perfect place for air and dirt separation: With the high temperature water flowing through the supply connections, this is the best possible point for air separation. irt separation takes place in the return connection, behind the radiators, and immediately before the boiler, thus protecting it from dirt. bar(g) kpa Flow resistance Flexalance bar(g) kpa Flow resistance Flexalance Plus Pressure loss [kpa - bar] Pressure loss [kpa - bar] Flow [m³/h] Flow [m³/h] PLL Ring Technology enefits Instead of using perforated plates (Flexalance) for air and dirt seperation, the Flexalance Plus uses our patented PLL ring technology, which has the following benefits: Shorter distance between supply and return connections possible. Even the smallest micro-bubbles and dirt particles are separated. Reduced flow-rate prevents heat exchange between the cold return water and the hot supply water. onsiderably greater thermal yield than other hydraulic balancers on the market.

Flexbalance EcoPlus : Perfect alance ombined with the Ultimate Output Unprecedented output and a compact format. Those are the most significant benefits of the Flexbalance EcoPlus. This very efficient hydraulic balancer for heating systems ensures heat transfer of no less than 99 per cent! The in- and outlets are connected in the bottle of the Flexbalance EcoPlus, by half-open pipes. This ensures that the upper or supply and under or return flows stay balanced, while thermal losses are minimized (no warming up of the return flow to the boiler). This immediately explains the unequalled output: the thermal exchange between the flows remains at a minimum. Moreover, the ingenious design ensures particularly low flow resistance. The enefits of the Flexbalance EcoPlus ompact. Heat transfer level of 99% (demonstrably the market leader). Low flow resistance. Flexvent Top W automatic air vent. Stepped galvanized connections. Stepped connections make the bubbles bump against the wall of the bottle and coalesce. Immersion pipe For temperature sensor. Half open pipes. t the top, the connection pipes open upwards, guiding the bubbles to the de-aerator. t the bottom they open downwards, guiding the dirt particles to the dirt separator. This also keeps the hot water in the upper section separate from the cold water beneath it. Insulation included. Incremental cross-wise plates. irt particles that are in the water are captured between several incremental cross-wise plates under the pipe. irt drainage tap.
