ACE GIKEN BP-105D-X-SUS Precision Liquid Dispensing Valve

Overview

The ACE GIKEN BP-105D-X-SUS is a high-reliability, pneumatically actuated precision liquid dispensing valve engineered for repeatable, low-volume fluid metering in automated manufacturing and laboratory environments. It operates on the principle of positive displacement via a resilient PTFE-coated diaphragm actuated by controlled compressed air—eliminating sliding seals and minimizing particle generation. Unlike solenoid or needle-valve architectures, this design delivers consistent cut-off performance under vacuum conditions and maintains long-term stability across repeated cycles. The valve is specifically optimized for low- to medium-viscosity fluids (typically <50,000 mPa·s), including aggressive chemistries such as ketones, alcohols, esters, aqueous buffers, silicone-based adhesives, epoxy resins, and medical-grade silicone elastomers. Its compact form factor (Ø22 mm × 78 mm L), lightweight construction (~420 g), and 360° rotational mounting capability enable seamless integration into multi-axis dispensing systems, benchtop dispensers, and inline process lines where spatial constraints and orientation flexibility are critical.

Key Features

• Bag-Nut modular diaphragm assembly enables rapid, tool-free replacement without disassembling the entire valve body—reducing maintenance downtime and eliminating calibration drift after servicing.
• Full-wetted path constructed from electropolished SUS316 stainless steel and virgin PTFE ensures exceptional chemical resistance and compliance with ISO 10993-5 cytotoxicity requirements for biocompatible fluid handling.
• Pneumatic 5-port configuration supports external pressure regulation and independent control of pilot and main flow paths—enabling precise dwell time modulation and pressure ramping for shear-sensitive materials.
• Consistent minimum dispense volume of 0.01 mL with ≤±1.5% volumetric repeatability (measured at 0.1 mL @ 0.45 MPa, water, 23°C, 100 cycles) verified per ISO 8503-2 surface roughness standards on wetted surfaces.
• Rated Kv value of 3.42 L/min (ΔP = 1 bar, water) reflects optimized internal flow geometry, minimizing turbulence and residence time—critical for preventing solvent evaporation or premature cure in reactive formulations.
• Mounting flange features dual O-ring grooves and symmetrical torque distribution, supporting secure fixation under vibration per IEC 60068-2-6 (5–500 Hz, 1.5 mm peak-to-peak).

Sample Compatibility & Compliance

The BP-105D-X-SUS is validated for use with non-abrasive, low- to medium-viscosity liquids compatible with SUS316 and PTFE—including organic solvents (e.g., acetone, IPA, THF), aqueous solutions (pH 2–12), silicone oils (10–10,000 cSt), UV-curable acrylates, two-part epoxies (pre-mixed), and medical-grade RTV silicones. It is not rated for abrasive slurries, high-viscosity pastes (>100,000 mPa·s), or halogenated acids (e.g., HF, HCl >10%). All wetted components comply with USP Class VI and FDA 21 CFR 177.1550 for indirect food contact. The valve meets CE marking requirements under the Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU for Category I equipment. Documentation includes material traceability certificates (MTRs) for SUS316 and fluoropolymer lot numbers.

Software & Data Management

While the BP-105D-X-SUS is a standalone pneumatic component, it integrates natively with industrial PLC-controlled dispensing platforms (e.g., Beckhoff CX series, Siemens S7-1200) via standard 24 VDC digital I/O and analog pressure transducer feedback. When paired with ACE GIKEN’s optional DP-2000 series controller or third-party motion controllers supporting pulse-width modulation (PWM) timing, full audit trails—including dispense count, cycle timestamps, pressure log data, and maintenance alerts—can be exported in CSV or OPC UA format. Such configurations support GLP/GMP environments requiring 21 CFR Part 11-compliant electronic records when deployed with validated software layers.

Applications

• Micro-dosing of conductive adhesives and underfill materials in semiconductor packaging and MEMS assembly.
• Precision application of medical-grade silicone sealants during catheter and implant housing assembly.
• Controlled dispensing of UV-curable optical adhesives in lens bonding and optoelectronic module fabrication.
• Pharmaceutical R&D workflows involving low-volume buffer exchange, reagent spotting, or formulation screening.
• In-line dispensing of functional coatings (e.g., anti-fog, hydrophobic) onto automotive sensors and display substrates.

FAQ

Is the BP-105D-X-SUS suitable for sterile or aseptic processing?
No—it lacks autoclavability or gamma sterilization validation. For sterile applications, consider ACE GIKEN’s BP-105D-X-SUS-STERILE variant with ethylene oxide (EO) bioburden certification.
Can the valve be used with corrosive acids like nitric acid?
Not recommended. While SUS316 offers broad corrosion resistance, concentrated oxidizing acids exceed its passivation limits. Consult ACE GIKEN’s chemical compatibility matrix before deployment.
What is the expected service life of the PTFE diaphragm?
Under nominal operating conditions (0.45 MPa, 23°C, water-like fluid), diaphragm life exceeds 5 million cycles; lifetime decreases predictably with elevated temperature, pressure, or abrasive particulates.
Are nozzles included with the valve?
No—nozzles are sold separately to allow customization of orifice size (100–500 µm), length, and taper angle based on fluid rheology and deposit geometry requirements.
Does the valve support closed-loop pressure control?
Yes—when integrated with an external proportional pressure regulator (e.g., SMC ITV series) and feedback sensor, real-time pressure modulation is fully supported via analog 4–20 mA or 0–10 V input.
