Manual Balancing Valve

Description

Heating and cooling systems designed with a constant flow principle circulate large amounts of water. To do that as efficiently as possible, it is important to ensure that the design flows in the different parts of the system are correct. Manual balancing valves are the best option in these types of systems.

What is a Manual Balancing Valve?

ZECO manual balancing valve is designed for accurate hydronic balancing in many applications. It is most often used for heating or cooling systems with domestic water.

Festures of Manual Balancing Valve

Broad product range

With valves in sizes from DN 15 up to DN 50, mounting options with internal thread, external thread or flanges and availability of measuring tools and accessories, there is always a ZECO manual balancing valve that corresponds to your requirements.

Compact construction

All ZECO balancing valves are designed to take up minimum space and be easy to install.

Working Principle of Manual Balancing Valve

Manual balancing valve is a special function valve. It has good flow characteristics. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal. As long as the balance valve with appropriate specifications is installed in each branch and user’s entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value.

Installation and Commissioning of Manual Balancing Valve

This valve can be installed either on the water supply pipe or on the water return pipe. Generally, it is recommended to be installed on the water return pipe, especially on the high-temperature loop.
