Diaphragm Pressure Reducing valves are also sometimes known as pressure regulators, as they are used to protect against the effects of high level water pressures. Basically Municipal and private water supply companies use pumps and pumping stations to boost water supply pressure in supply mains, so that they should be able to supply water for fire fighting, high rise building to overcome loss of pressure as the altitude increases, and to maintain water supply in water towers and supply tanks. Pressure in water supply mains can exceed 200 psi.

| using method |
vacuum & safety valves is suitable for all kinds of water heaters and the container and steam system. When water heater and steam system present the vacuum state, can open the system that originally closed automatically, make it dispel the vacuum state that may appear while entering air. Prevent from because siphon water in being function systematic take out and cause container collapse or water heater wait for device to be braised to burn. |

| MAIN CHARACTERISTICS AND USES |
The RA thermostatic mixings valves are used in hot water systems for sanitary use. They keep the temperature of mixed water supplied to the user constant even when the condition listed below vary:
The RA thermostatic mixing valves have a temperature range that is ideal for heating a centralized water system with heater . They also have an internal anti-limestone lining. OPERATION :The valves were designed to supply domestics hot water at an adjustable and constant temperature where no other regulating system is present. The very sensitive thermostatic elements is positioned centrally inside the out going stream union and its guides a regulating shutter which adjusted the ingoing cold water flow to the hot water flow according to the required water temperature . The knob can be used to regulate the temperature of the outgoing water. MATERIALS :

This automatic air vent valve is a single float valve designed for solar thermal energy plants, and carries out two main functions: the evacuation of a consistent air flow through the system (e.g. during loading/pressurization of the plant), and degassing which discharges air trapped in the pipeline, while functioning, in particular in the solar collectors. This valve has a paramount importance in solar thermal energy plants, evacuating and discharging trapped air in the pipelines and in the solar collectors. As a matter of fact, the presence of oxygen in the system can provoke numerous negative phenomena such as anodic corrosion, localized noise, air pockets, obstructions, etc., which may significantly compromise the performance and integrity of the systems. These valves are usually installed at the summit of the primary circuit in a solar thermal energy plant, and are resistant to the high temperatures that the heat-transfer fluids can reach, even in stagnation phases. Their suitability for application in solar thermal energy plants conforms to EN 12976 and EN 12977.
| AUTOMATIC AIR VENT / AIR RELEASE VALVE | ||||||
| Automatic air vent valve prupose of installation in hot & cold water system to eliminate entrapped air in water lines. Prevent air locking due to filling of system or while priming of pump systems to increase thermal efficiency. To increase thermal efficiency fitted with check valve to prevent air being drawn back into system or water escaping from port event. | ||||||

The Thermostatic mixing valve (TMV) is installed in sanitary systems, in order to obtain energy savings, comfort when using hot water, avoiding the risks of burns caused by extremely high working temperatures. It can be installed in a boiler room on the main hot water sanitary columns, next to wall boilers or water accumulation boilers, or in the distribution cabinets in case of manifold pliable sanitary systems.
