Application scenarios
Fluid Flow Control in Pipeline Systems
For fluid flow control in pipeline systems, using wafer installation, suitable for nominal diameters from DN 50 to DN 600, with a maximum working pressure of 16 bar and support for EN 1092 flange connections.
Single-Flange Installation at Pipeline Ends or Equipment Connections
Suitable for single-flange installation at pipeline ends or equipment connections. The single-flange installation pressure is 3 bar for DN 50 to DN 250 and 2 bar for DN 300 to DN 600. The valve supports EN 1092 PN 6/10/16 and ASME Class 150 connection standards.
Selection points
Vulcanized Seat
Features a vulcanized seat design and is suitable for wafer butterfly valve selection where the seat sealing structure is a key consideration.
Three-Bushing Stem Support
The stem is equipped with three bushings to prevent stem deflection and help maintain stable stem operation.
Precision-Machined Body and Disc with Low-Torque Operation
The body and disc are precision-machined for low operating torque, making the valve suitable for applications with specific operating torque requirements.
Restricted-Pressure Single-Flange Installation
Supports single-flange installation; the allowable pressure is 3 bar for DN 50-DN 250 and 2 bar for DN 300-DN 600.
Vacuum Service Capability
Supports vacuum service at an absolute pressure of 0.001 bar and is suitable for piping systems with defined vacuum limits.
Installation in Any Orientation
The valve supports installation in any orientation, making it suitable for piping layouts requiring flexibility in the installation direction.
FAQ
Which pipeline connection standards and flange facings are compatible with the Ebro Z011-B wafer butterfly valve?
The Z011-B uses a wafer connection and is compatible with EN 1092 PN 6, PN 10, and PN 16 flanges, as well as ASME Class 150 flanges. It can be used with EN 1092 Form A/B and ASME RF and FF flange facings. During selection, verify the pipeline flange standard, facing type, and nominal diameter.
What are the pressure, temperature, and vacuum service ranges of the Z011-B wafer butterfly valve?
The valve has a maximum working pressure of 16 bar and a working temperature range of -10°C to +120°C. The actual allowable temperature depends on pressure, medium, and valve materials. Vacuum service is available down to 0.001 bar absolute pressure.
Can the Z011-B be installed with a single flange?
Yes. Under single-flange installation conditions, the allowable pressure is 3 bar for DN 50 to DN 250 and 2 bar for DN 300 to DN 600. Single-flange installation should be verified according to the applicable nominal diameter and pressure limits.
What is the sealing performance of the Z011-B, and what seat design does it use?
The Z011-B uses a vulcanized seat, with sealing performance compliant with EN 12266 Leakage Rate A and ISO 5208 Category 3. The body and disc are precision-machined to help reduce operating torque, and the stem is fitted with three bushings to prevent stem deflection.
How can the Z011-B be equipped with manual, pneumatic, or electric actuators?
The valve top flange complies with EN ISO 5211 and can be used as the actuator mounting interface. For the actual actuator configuration, confirm the actuator specification based on the valve size, required operating torque, and specific service conditions.
