Technical Specifications

Applicable Fluid Temperature

The applicable temperature range depends on the sealing material:

• Normal temperature type (NBR sealing): -9°C to 80°C

• Special high-temperature type (PTFE sealing): -29°C to 150°C

Please select the appropriate sealing material and temperature specification according to the actual operating conditions.

Model and Size Range

The C760 and C763 series are available in the following nominal sizes:

• DN25

• DN32

• DN40

• DN50

• DN65

The standard connection is internal thread. ZG (PT) is the conventional thread type. M, G, NPT and other thread types can be customized in batches according to user requirements.

Three-Way Valve Configuration

The C763 three-way valve supports both diverting and mixing applications. Its flow direction changes according to the valve core position and control operation.

The three-way configuration can be selected according to the required pipeline arrangement and system flow-control function.

Installation and Control

The actuator must be installed vertically upwards. A manual operating device can be selected as an option.

The series supports open/closed control, while the regulating models support proportional control through 4–20mA DC or 0–10V DC signals. Please refer to the product-specific wiring diagram for electrical connections.

Applications

The BEST C760/C763 Series Micro Electric Valves are designed for water systems in:

• Heating systems

• Ventilation systems

• Air conditioning systems

• HVAC water circulation and flow-control applications
