1、 Electric Clamp Ventilation Butterfly Valve D971W-10 Product Overview

Electric clamp ventilation butterfly valve D971W-10It is an electrically driven clamp type ventilation butterfly valve, suitable for ventilation, air conditioning, environmental protection, and industrial pipeline systems, used to regulate or cut off the flow of gases, dust, and other media. It has a compact structure and reliable sealing, especially suitable for high flow and low pressure drop working conditions.

Model analysis:

D: Butterfly valve

9: Electric actuator

7: Clamp on connection

1: Straight plate valve plate structure

W: The sealing surface material is stainless steel (or no sealing surface, please refer to the manufacturer's label for details)

10: The nominal pressure is PN10 (1.0MPa)

2、 Electric clamp ventilation butterfly valve D971W-10 structure and material

Valve body structure:

Connection method: Clamp type (flange hole spacing in accordance with national standard GB/T 12221), easy to install, and space saving.

Valve body material: carbon steel (WCB), stainless steel (304/316) or cast steel, selected according to the characteristics of the medium.

Valve plate: usually made of stainless steel plate (304/316), the surface can be plated with hard chromium or sprayed with wear-resistant layer, corrosion-resistant and lightweight.

Valve stem: Stainless steel integrated structure, high strength, wear-resistant.

Sealing material:

W-type: usually stainless steel metal hard seal, high temperature resistance (≤ 425 ℃); Some models use PTFE soft seals, which are corrosion-resistant but have lower temperature limits (≤ 150 ℃).

Electric actuator:

Power supply: AC220V/380V or DC24V (optional).

Control mode: switch type (fully open/fully closed) or adjustment type (4-20mA signal feedback, supporting proportional adjustment).

Protection level: IP67/IP68, suitable for humid or dusty environments.

Optional functions: manual operating mechanism, limit switch, overload protection.

3、 Technical parameters of electric clamp ventilation butterfly valve D971W-10

project	Parameter Description
Nominal diameter (DN)	DN50、DN65、DN80、DN100、DN125、DN150、DN200、DN250、DN300
Nominal Pressure	PN10（1.0MPa）
Applicable Temperature	Metal seal: -29 ℃~425 ℃; Soft seal: -20 ℃~150 ℃
Applicable Medium	Air, smoke, dust, non corrosive gases, etc
leakage level	Metal seal: ≤ 1% x valve rated capacity; Soft seal: zero leakage
flow characteristics	Approximately equal percentage (adjustable type)
Actuator torque	Match according to valve diameter (e.g. DN300 requires high torque actuator)

4、 Product Features

Lightweight and compact: The clip on design reduces installation space and is suitable for areas with dense pipelines.

Low flow resistance design: The valve plate has a straight through structure, which reduces pressure loss when the medium passes through.

High sealing performance: Metal hard seal is resistant to high temperature and high pressure, while soft seal is suitable for clean gas zero leakage.

Intelligent control: The electric actuator supports remote automation control and can be integrated into DCS/PLC systems.

Long lifespan: The valve stem is connected to the valve plate without a pin, avoiding looseness and being wear-resistant and corrosion-resistant.

5、 Application Fields

Ventilation system: Adjustment of building HVAC supply and exhaust ducts.

Environmental engineering: Dust collector, flue gas control for desulfurization and denitrification systems.

Industrial pipelines: powder transportation, boiler flue, chemical plant gas management.

Energy industry: cutting off of gas and heat pipeline media.

6、 Precautions for selection of electric clamp type ventilation butterfly valve D971W-10

Medium characteristics: For corrosive gases, stainless steel valve body and hard seal should be selected; It is recommended to seal the dust medium with metal to prevent wear and tear.

Temperature and pressure: High temperature resistant actuators should be selected for working conditions exceeding 200 ℃.

Control requirement: When adjusting the flow rate, a 4-20mA feedback regulating actuator should be selected.

Installation direction: It is recommended to install horizontally. If installing vertically, the load-bearing capacity of the actuator needs to be confirmed.

7、 Installation and maintenance

Installation steps:

Clean the flange surface of the pipeline to ensure there are no impurities.

Clamp the valve between the flanges and tighten the bolts diagonally and evenly.

After wiring, test the forward and reverse rotation of the actuator and adjust the limit switch.

Maintenance points:

Regularly check the wear of the sealing surface.

Lubricate the actuator gearbox every 2 years.

Long term disuse requires closing the valve and disconnecting the power supply.

8、 Common fault handling

Fault phenomenon	Possible reasons	solution
Valve leakage	Sealing surface wear/impurity blockage	Clean or replace the sealing ring
The actuator does not operate	Power failure/insufficient torque	Check the circuit and replace the high torque actuator
Valve card stuck	Crystallization of the medium or rusting of the valve stem	Clean the valve, add lubricant to the valve stem

9、 Manufacturing standards

Manufacturing standards: GB/T 12238 (National Standard), API 609 (American Standard).
