Overview
The Cole-Parmer 01540-01 Solenoid Valve and Pressure Regulator Assembly is an integrated fluid control solution engineered for precise, repeatable pressure management and on/off actuation in laboratory gas and low-viscosity liquid delivery systems. Unlike standalone valves or regulators, this unit combines a normally closed solenoid valve and a high-stability diaphragm-type pressure regulator within a single compact, leak-tight brass housing. It operates on 24 VDC—compatible with standard lab power supplies and programmable logic controllers (PLCs)—and delivers stable downstream pressure across variable flow conditions, making it suitable for applications requiring dynamic pressure setpoint control without external feedback loops. Its design adheres to fundamental pneumatic control principles: the solenoid actuates the valve seat via electromagnetic force, while the regulator maintains constant outlet pressure through spring-loaded diaphragm compensation against upstream fluctuations. This dual-function architecture reduces system complexity, minimizes potential leak points, and improves long-term calibration stability compared to discrete component configurations.
Key Features
- Integrated construction eliminates inter-component tubing, reducing dead volume and improving response time during pressure transitions.
- Viton® elastomer seals ensure chemical compatibility with common laboratory gases (N₂, CO₂, compressed air) and mild solvents, supporting extended service life under intermittent duty cycles.
- Adjustable outlet pressure range (0–60 psi) enables fine-tuning for sensitive instrumentation interfaces—including mass flow controllers, gas chromatography inlets, and reactor purge lines.
- Brass body provides mechanical robustness and thermal stability across ambient lab temperatures (10–40°C), minimizing drift due to thermal expansion mismatch.
- UL Recognition and CE marking confirm compliance with electrical safety standards (IEC 61000-6-2/6-3) and electromagnetic compatibility requirements for use in regulated laboratory environments.
- 1/4″ NPT female ports facilitate direct connection to standard lab-grade tubing adapters and stainless-steel manifolds without custom fittings.
Sample Compatibility & Compliance
The 01540-01 is validated for use with non-corrosive, particle-free gases and low-surface-tension liquids (e.g., deionized water, ethanol, isopropanol). It is not rated for aggressive acids, halogenated solvents, or slurries. For GLP/GMP-aligned workflows, the device supports traceable operation when paired with validated control systems: its continuous-duty rating and stable pressure hysteresis (< ±1.5% of full scale) enable reproducible method execution across multiple shifts. While the unit itself does not carry ISO 17025 accreditation, its performance characteristics align with ASTM F2784 (Standard Practice for Evaluating Pneumatic Components in Medical Gas Systems) and ISO 8573-1 Class 4 purity requirements when installed downstream of appropriate filtration (0.01 µm coalescing filter recommended).
Software & Data Management
As a hardware-level control component, the 01540-01 operates independently of software; however, it is fully compatible with industry-standard automation platforms including LabVIEW™, Python-based PyVISA instrument control libraries, and Beckhoff TwinCAT PLC environments. When integrated into a larger system, its 24 VDC input allows seamless interfacing with digital I/O modules that support event logging, cycle counting, and timestamped actuation records—essential for audit trails under FDA 21 CFR Part 11 when used in pharmaceutical process development or analytical method validation. No proprietary drivers or firmware updates are required.
Applications
- Automated gas purging of HPLC autosampler trays and detector cells.
- Pressure stabilization for headspace samplers and purge-and-trap concentrators.
- Controlled inert gas blanketing in glovebox antechambers and reaction vessel vent lines.
- Modulated carrier gas supply in benchtop FTIR and Raman spectrometers with optional flow modulation accessories.
- Sequential reagent delivery in automated titration and dissolution testing systems where pressure consistency directly impacts volumetric accuracy.
FAQ
Is the 01540-01 suitable for vacuum service?
No—it is designed exclusively for positive-pressure applications up to 100 psi inlet pressure and cannot be used as a vacuum breaker or vacuum regulator.
Can this valve be mounted in any orientation?
Yes, but horizontal mounting with ports facing upward is recommended to prevent condensate accumulation in the regulator chamber.
Does it include internal filtration?
No—external particulate filtration (e.g., 5 µm sintered stainless-steel filter) is required upstream to prevent solenoid armature seizure.
What is the expected service life under continuous cycling?
Rated for ≥1 million cycles at rated load; actual lifespan depends on media cleanliness, operating temperature, and voltage stability.
Is calibration documentation provided with shipment?
Factory verification data (pressure linearity, leakage rate <1 × 10⁻⁶ mbar·L/s He) is included; NIST-traceable calibration certificates are available upon request at additional cost.
