What is the difference between relief valves and mixing valves?

Relief valves are designed to protect a system from overpressure by releasing excess pressure. They are typically set to open at a specific pressure threshold and allow the pressure to escape, preventing damage to the system. Relief valves are commonly used in heating and cooling systems, as well as in steam and water boilers. Mixing valves, on the other hand, are used to control the temperature of water by blending hot and cold water streams. They are commonly used in plumbing systems, such as in showers or sinks, to prevent scalding by regulating the water temperature. Mixing valves work by adjusting the flow rates of the hot and cold water, ensuring that the desired temperature is achieved.

How do I choose the correct pressure regulators for my needs?

• Identify the desired outlet pressure range, including the minimum and maximum pressures required for your application.
• Determine the required flow rate for your application and ensure that the regulator can handle the required flow.
• Ensure that the regulator is compatible with the fluid or gas being regulated, as well as any other components in the system.
• Choose a regulator made of materials that are suitable for the conditions of your application, including temperature, pressure and the corrosive nature of the fluid or gas.
• Consider additional features such as pressure gauges, diaphragm materials and inlet/outlet connections.
• Determine whether the regulator will be used in a hazardous or explosive environment and ensure that it meets any necessary safety requirements.
• Select a regulator from a reputable manufacturer with a history of producing high-quality, reliable products and good customer service.

How does a thermostatic mixing valve work?

A TMV uses a thermostatic element to sense the temperature of the mixed water and adjust the hot and cold water flow to maintain a set temperature.
