Description

Features:

• Body composition and flexibility, can be adapted to the needs of different pressure
• Chosen hysteresis synchronous motor, a magnetic hysteresis clutch protection, can produce stable torque in the case of the valve can still pause at any position;
• Reversing control: can be flexibly flexible wiring reversing, to match different body;
• valve flange connection, constructed in accordance with IEC international standards;

• When indicated on design drawings without valve installation position, the control valve is usually installed in the return pipe road
• Former Install the regulator to clean the pipes, valves, filters to be installed on the inlet side
• Reserve enough space for installation, for maintenance
• Consistent with the direction of the arrows ☆ valve body and the valve on the flow medium
• Drive can not be covered with insulation material, to prevent the drive cooling equipment adversely.
