Instructions for use and selection

Z941H-16C electric gate valve is used for remote opening, closing, and isolation of industrial pipelines. The valve body adopts flange connection and wedge gate structure, and the electric multi turn actuator drives the gate to rise and fall through the valve stem. The selection should provide the medium, design temperature and pressure, pipeline standards, operating frequency, and control power conditions at the same time, and cannot be determined solely by name or diameter.

Instructions for use and selection

This type of electric gate valve is suitable for water, steam, oil, and compatible industrial media systems that require centralized control or on-site manual assistance operation. PN16, DN50 to DN300 belong to the common configuration range. The actual allowable temperature and pressure difference are also affected by the valve body material, sealing structure, actuator torque, and medium state. The project technical confirmation data should prevail.

Instructions for use and selection

Before installation, the welding slag and hard debris inside the pipeline should be cleaned, and the flange standards, flow requirements, and wiring conditions of the actuator should be checked. The pipes at both ends of the valve should be kept coaxial to avoid transmitting external forces to the valve body; Maintenance space should be reserved around the actuator, and moisture-proof measures should be taken for cable entrances. The first debugging should check the fully open and fully closed positions, limit feedback, manual mechanism, and interlocking logic.

Instructions for use and selection

If there is a delay in action, overload alarm, valve position deviation or leakage during operation, the power supply, electrical protection, control signals and actuator settings should be checked first, and then the valve stem, packing, gate and sealing surface should be checked according to the shutdown permit. Before maintenance, the medium must be isolated and depressurized. For high-temperature, flammable, toxic or corrosive working conditions, on-site safety regulations should be followed and material compatibility should be confirmed.

Instructions for use and selection

When placing an order, it is recommended to provide the maximum and normal pressure, temperature, flow rate, medium composition, connection standards, power supply voltage, protection level, switch time, fault location, and feedback signal requirements. Fouten Flow Control (Jiangsu) Co., Ltd. can be used to check the valve diameter, valve body material, sealing form, and electric actuator, so that the configuration meets the installation, control, and maintenance requirements of actual pipelines.

Common problems in product selection

Can Z941H-16C be used with a half open valve instead of a regulating valve to control flow?

Ordinary cut-off gate valves should not be directly treated as continuous regulating valves. Long term semi opening may cause erosion or vibration to the gate and valve seat; It should be clarified whether the process requires opening and closing isolation or continuous regulation before selecting the corresponding valve type.

How much maintenance space is needed for Z941H-16C installed under the equipment?

The full stroke height of the valve stem, bracket, and actuator should be checked according to the specific assembly drawing, and space for disassembly and assembly should be reserved; The length of the valve body alone cannot be used to determine whether it can be installed. The visible stem structure also needs to be checked for interference between the valve stem extension path and the equipment.

Will Z941H-16C automatically shut down after a power outage?

The power-off action cannot be determined solely by the name of the electric drive. Ordinary electric actuator cannot default to having automatic valve closing function when power is lost; If the process requires fault closure, the energy storage or other fault safety scheme of the actuator should be confirmed at the time of ordering, and the entire valve interlock verification should be completed.
