The DN80 Butyl-Lined Valve paired with the C Series Actuator delivers high-performance flow control for systems requiring chemical resistance and consistent actuation. Designed for installations where corrosive fluids or hygiene-sensitive media are present, this combination addresses frequent industry challenges such as premature lining degradation, inconsistent actuation, or high manual handling costs.
Key Technical Details and Industry Standards
This DN80 valve adheres to EN 558-1 Series 1 face-to-face standards and comes with a high-grade butyl rubber lining—ideal for general chemical resistance, particularly with diluted acids and alkalis. The valve body is cast to DIN standards and built for long service life under moderate temperatures and pressures.
- Size: DN80
- Face-to-Face Standard: EN 558-1, Series 1
- Lining: Butyl rubber (IIR) – high chemical resistance
- Pressure Rating: Up to PN10 depending on actuator selection
- Temperature Range: -10°C to 120°C (media-dependent)
- Certifications: ISO 9001, WRAS (lining variant), PED 2014/68/EU-compliant
This product shares compatibility with rubber-lined straight-through diaphragm valves, particularly in processing environments requiring similar media handling.

Where This Valve Performs Best
The DN80 Butyl Valve with C Series Actuator is suited to chemical processing, wastewater treatment, and certain food and beverage environments where abrasion resistance and low particle adhesion are essential. It integrates smoothly with existing automated systems and is compatible with PLC-controlled operations.
- Chemical dosing skids
- Acid-neutralisation pipelines
- Wash-down fluid lines
In these settings, the butyl lining protects against early wear from aggressive media, while the actuator ensures precise and remote-controlled operation—minimising the need for manual intervention and increasing operational safety.

Engineering Considerations and Lining Benefits
Butyl rubber offers a smooth internal surface, minimising buildup and scaling in systems that handle mineral-laden or abrasive slurries. Compared to EPDM or natural rubber linings, butyl performs better in low-permeability environments and shows improved ageing characteristics under intermittent temperature loads.
The valve’s bonnet and body are designed for easy disassembly, allowing for diaphragm or lining replacement without requiring full unit removal. The C Series actuator, available in pneumatic and electric variants, includes adjustable torque settings and visual position indicators for enhanced process transparency.
Durability is reinforced by a modular construction and corrosion-resistant fasteners, helping extend the valve’s lifecycle in demanding installations. If you’re exploring other material linings, our plastic-lined diaphragm valves may also be of interest for aggressive chemical services.

Frequently Asked Questions – DN80 Butyl Lined Actuated Valve
Q1: What makes the DN80 Butyl Valve suitable for corrosive media?
The butyl lining offers high chemical resistance, especially against diluted acids and alkalis, making it reliable in aggressive fluid environments.
Q2: Can the C Series Actuator be used with a PLC or smart control system?
Yes. The actuator includes input/output signal compatibility and feedback positioning, supporting full integration into automated systems.
Q3: How does this valve differ from older models?
This generation features enhanced lining adhesion, improved actuator responsiveness, and modular construction for quicker servicing.
Q4: Are spares readily available globally?
Yes, replacement diaphragms, liners, and actuator spares are available through our authorised service network and stocked regionally.
Q5: Can this valve be customised?
Customisation options include alternative lining materials (EPDM, PTFE), different actuator types, and flange configurations upon request.
Case Snapshot: Improving Uptime in European Manufacturing
A manufacturing plant in Germany recently adopted this DN80 valve unit in its acid neutralisation system. By switching from a manually operated model to the C Series Actuator version, they reported a 22% reduction in maintenance-related downtime over six months—primarily due to quicker actuator feedback and longer lining durability.
