Electric Sanitary Ball Valves

Tri-Clamp Quick-Release Series

Engineered for fast-turnaround sanitary pipelines (DN15 to DN100 / 1/2" to 4"). Incorporates precision sanitary clamp ferrules compliant with ASME BPE, 3-A, and ISO 2852 standards. Allows tool-free pipeline disassembly for routine inspection, swab testing, and manual maintenance.

• Tool-less clamp ferrule quick assembly and disassembly
• 100% full-port design delivers unimpeded turbulent-free liquid flow
• Self-draining internal profile minimizes batch product holdup

Orbital Butt-Weld Pharma Series

Designed for high-purity bioprocessing loops, Water-for-Injection (WFI), and ultra-pure clean steam systems (DN15 to DN100 / 1/2" to 4"). Features extended weld ends with controlled sulfur content optimized for automatic orbital tube welding without disassembling the valve.

• Conforms strictly to ASME BPE extended tang dimensions
• Eliminates elastomeric clamp gaskets in permanent cleanroom loops
• Withstands continuous SIP steam cycles up to 150°C (302°F)

Full Cavity-Filled PTFE Seats

Standard ball valves have dead space between the ball and body where media stagnates and ferments. DELCO utilizes solid virgin PTFE cavity fillers that occupy 100% of this cavity, eliminating bacterial breeding grounds.

Electropolished Bore (Ra ≤ 0.4 µm)

All wetted stainless components receive high-grade mechanical polishing followed by electrochemical polishing, achieving an ultra-smooth finish of Ra ≤ 0.4 µm (16 µin). Guarantees flawless CIP flushability without residue adhesion.

3-A, FDA & USP Class VI Compliance

All elastomeric compounds and PTFE cavity seats comply with FDA 21 CFR 177.2600 and USP Class VI toxicological testing. Fully documented for integration into validated biopharmaceutical and infant nutrition processes.

Forged Low-Carbon 316L Stainless

Constructed exclusively from forged AISI 316L (1.4404) with low carbon content (C ≤ 0.03%). Prevents intergranular sensitization during welding and provides superior resistance to acidic sanitizers and hot caustic CIP washes.

Washdown-Resistant IP67/IP68 Actuator

Sanitary packaging rooms require daily chemical hosedowns. Actuators feature sealed IP67/IP68 enclosures, smooth crevice-free epoxy coatings, stainless fasteners, and washdown-safe electrical cable glands that resist caustic wash sprays.

Aseptic Dosing & Modulating Control

Equipped with high-precision electric actuators capable of fast 5–8 second On/Off cutoff or intelligent 4–20mA modulating flow metering. Delivers exact liquid recipe dosing for automated dairy, beverage blending, and cosmetic skids.

1. Why are full cavity-filled PTFE seats mandatory in sanitary ball valves?

In conventional ball valves, a hollow annular space exists between the exterior of the ball and the valve body shell. In food or pharmaceutical processes, liquid enters this cavity and cannot be washed away during CIP, causing media stagnation, microbial decomposition, and bacterial contamination. DELCO sanitary valves incorporate solid, precision-machined virgin PTFE cavity fillers that encapsulate the ball completely, eliminating dead space and ensuring 100% CIP flushability.

2. What is the significance of the Ra ≤ 0.4 µm internal electropolished finish?

Microscopic surface irregularities on unpolished stainless steel provide shelter for bacteria, proteins, and chemical residues to form tenacious biofilms. An electropolished finish of Ra ≤ 0.4 µm (16 micro-inches) smooths out microscopic peaks and valleys chemically, passivating the surface with an enriched chromium-oxide layer. This ensures non-stick fluid flow, complete self-drainability, and compliance with ASME BPE bioprocessing standards.

3. Can DELCO electric sanitary valves withstand continuous CIP washing and SIP sterilization?

Yes. The valves are engineered to withstand standard CIP cleaning solutions (such as 2% to 3% hot sodium hydroxide at 85°C and dilute nitric acid neutralization) without elastomer degradation. For sterilization, our high-density virgin PTFE cavity seats and live-loaded stem seals endure saturated clean steam at 135°C to 150°C (SIP cycles) for up to 60 continuous minutes.

4. Can the electric actuator survive aggressive daily washdowns in food plants?

Yes. Food and beverage packaging facilities perform intense daily washdowns using high-pressure hot water and sanitizing foam. DELCO electric actuators are rated to IP67/IP68 and feature smooth external contouring with electrostatic polyurethane coatings and 304 stainless steel hardware, preventing water accumulation and resisting chemical spray corrosion.
