Product Specification

DINKONDA GLOBAL Power Plants Special Z940/Z941 Series PN16/25/40/64/100, Manual Emergency Handwheel, Multi Turn Electric Actuator Wedge Gate Valve

Product Overview
The Z940/Z941 electric gate valve is a flange connected, rising stem wedge gate structure, equipped with a multi turn electric actuator, and comes with a manual emergency handwheel. By driving the valve stem up and down with a motor, the gate can be driven to achieve full opening and full closing of the valve, which can be remotely controlled by electric means. In case of power failure, it can be manually operated on site. The specifications of this drawing are DN300, PN64, and the valve body material is WCB carbon steel. It is widely used in industrial pipelines such as power plants, petroleum, chemical, and metallurgical industries as a medium for cutting off pipelines. Z940 is a wedge-shaped rigid single gate, and Z941 is a wedge-shaped elastic single gate.

Structural Composition
WCB cast steel valve body, valve cover, rising stem valve stem, wedge gate, valve seat sealing pair, packing components, flange fasteners, multi turn electric actuator, manual operating wheel.
1. Valve body: WCB carbon steel casting, high pressure bearing, good structural strength, suitable for high temperature and high pressure working conditions;

2. Gate: Z940 rigid single gate, Z941 elastic gate, elastic gate can compensate for temperature deformation, and the sealing performance is more stable;

3. Valve stem: with a clear stem design, the valve stem can be raised and lowered to visually display the valve switch position, making it easy to observe the status on site;

4. Electric actuator: a multi turn electric device with electric switch, valve position feedback, and overload protection;

5. Configure manual wheels for emergency opening and closing in case of power failure;

6. Connection form: flange connection, easy to disassemble and maintain.

Core Features
1. Clear stem structure, exposed valve stem, intuitive valve opening and closing status, easy to inspect;

2. Direct flow channel, low medium resistance, and low pressure loss;

3. Dual operation mode of electric and manual, normal remote electric control, on-site manual operation in case of power failure, ensuring safety;

4. Wedge gate, which can automatically compensate for the wear of the sealing surface when closed, ensuring reliable sealing;

5. The electric actuator is equipped with built-in torque protection to prevent valve jamming and equipment damage;

6. Bidirectional pressure, the medium can flow in both directions, and there is no flow restriction during installation.
