Festo DFPC-80-50-D – Linear Drive for Process Valves | Bore 80mm, Stroke 50mm | Murali Pneumatics Coimbatore

Festo DFPC-80-50-D Linear Drive – ISO 5210 Process Valve Actuator

The Festo DFPC-80-50-D is a heavy-duty pneumatic linear drive from the DFPC series, purpose-engineered for actuating quarter-turn and linear process valves in accordance with ISO 5210. With an 80 mm piston bore, 50 mm stroke, and F07 flange hole pattern, this actuator slots directly onto ISO 5210-compliant valve stems without adapters. The DFPC series is rated for ATEX zones 1, 2, 21, and 22 — making it a go-to choice wherever process safety and explosion protection are mandatory.

Key Features

• ISO 5210 F07 Flange Compliance — Direct bolt-on mounting to standard process valve bodies; no custom adapters needed
• Double-Acting Operation — Air pressure drives both advance and return strokes for positive, reliable valve positioning in both directions
• 3016 N Advance Force at 6 bar — Sufficient thrust to actuate medium-duty gate, globe, and butterfly valves under process pressure
• ATEX Zone 1, 2, 21 & 22 Certified — Safe for use in flammable gas and combustible dust environments without additional enclosures
• High-Alloy Stainless Steel Piston Rod, Nut & Tie Rods — Corrosion-resistant construction for aggressive media, washdown environments, and outdoor installations
• Smooth-Anodised Aluminium Cylinder Barrel — Hard-wearing bore surface reduces seal wear and extends service life
• Elastic Cushioning at Both End Positions — Absorbs end-of-stroke impact (rated at 1.4 J) to protect the valve stem and actuator internals
• Proximity Switch Position Detection — Designed to accept standard proximity switches for valve open/close feedback to PLC or DCS
• Any Mounting Position — Unrestricted orientation allows integration into tight process skid layouts
• LABS (PWIS) Conformity to VDMA 24364 Zone III — Suitable for painting and finishing lines where silicone contamination must be avoided

Common Applications

• Chemical & Petrochemical Process Plants — Actuating gate and globe valves on process pipelines in ATEX-classified hazardous zones
• Food & Packaging Lines — Valve actuation on filling, dosing, and CIP (clean-in-place) systems; LABS conformity prevents finish defects downstream
• Mining & Metals Processing — Robust stainless steel construction handles abrasive media, high humidity, and aggressive wash-down in ore processing
• Water Treatment & Pump Houses — Outdoor installation in any orientation for motorised gate valve automation on large pipe manifolds
• Pharmaceutical & Biotech Facilities — Hygienic valve control with corrosion-resistant internals suitable for sterile process environments
• Foundries & Metal Casting — High ambient temperature tolerance (up to 80 °C) keeps it operational in furnace-adjacent valve automation
