| FCV2334 |
| FCV series fan coil electric two-way valve |
| Brief introduction: The new FCV driver is specially designed for the new valve body and can be used in various hot and cold coil control systems. It has the advantages of convenience, reliability and easy installation. The valve body can be installed on the fan coil, radiator or air handler first, and then the driver can be installed. The driver's multiple voltages and functions make installation easier, and are equipped with synchronous motors, spring-return operating functions that have been proven in hundreds of Orville valves. |
The driver has a normal closing differential pressure, a high closing differential pressure, normally open and normally closed, and is equipped with different voltages. The driver is directly connected to the valve body, which is fast, simple and requires no connection and calibration tools

Material description and technical data:
Installation and maintenance instructions:
1. The valve body is closed on the valve stem.
2. Before installing the valve, ensure that the pipeline is clean and free of oxide scale, metal pieces, sand, stone and other debris left on time by welding.
3. When the pipeline is connected to the valve body, it must be completely anastomated and not subject to vibration. The direction of water flow should be the same as marked on the valve body.
4. When the driver is installed vertically on the valve body, avoid the driver shape under the valve. Allow sufficient space to remove the actuator from the valve body during routine maintenance.
5. When the valve is maintained, the power must be cut off or isolated. The water system should not be under pressure.
6. For other installation requirements, please refer to the relevant provisions of "Driver".
| P74JA |
| P74JA Series Difference Controller |
| Introduction: P74JA series differential controller is usually used in water system to control the pressure difference between water pipes. After the SPDT floating point action of the controller turns on the contact, the motor drives the longitudinal valve. A typical application is: the valve is installed in the bypass pipeline near the system water pump. When the system pressure difference increases and exceeds the set value of the controller, the valve opens further, and more water turns to flow through the bypass valve. , So that the system pressure difference is reduced. Conversely, the pressure difference causes the valve to close and the pressure difference in the system increases. |
