Overview
The Deepflow CYMQ000PR Inlet Pressure Regulator Assembly is an engineered subsystem designed for integration into ultra-pure water (UPW) generation and distribution systems. It functions as a precision pressure control module positioned upstream of critical purification stages—including reverse osmosis (RO) membranes, electrodeionization (EDI) units, and final polishing cartridges—to ensure stable, consistent feed pressure across variable municipal or pretreated water supply conditions. Operating on the principle of direct-acting spring-loaded diaphragm regulation, the assembly maintains setpoint accuracy within ±0.02 MPa under dynamic flow loads (0.5–10 L/min), thereby preventing pressure-induced membrane compaction, premature fouling, and flow instability that compromise resistivity (>18.2 MΩ·cm), total organic carbon (TOC) removal (<1 ppb), and particle integrity in Class 1 UPW applications per ISO 3696 and ASTM D1193 Type I specifications.
Key Features
- Stainless steel 316L body and wetted components for corrosion resistance and leachate-free operation in high-purity water service
- Adjustable setpoint range: 0.1–0.6 MPa (14.5–87 psi), calibrated with traceable NIST-traceable pressure standard
- Integrated dual-stage filtration (5 µm sintered stainless steel pre-filter + 1 µm pleated PTFE secondary filter) to protect downstream RO/EDI elements from particulate ingress
- Integrated pressure gauge (0–1.0 MPa, 1.6% FS accuracy) with glycerin-filled housing for vibration damping and readability in laboratory environments
- ASME B16.5 Class 150 flanged inlet/outlet ports (DN15 / 1/2″ NPT optional) compatible with standard UPW piping protocols (electropolished 316L tubing, orbital welds)
- Compliance-ready documentation package including material certifications (EN 10204 3.1), RoHS Declaration, and CE marking per PED 2014/68/EU Annex I essential safety requirements
Sample Compatibility & Compliance
The CYMQ000PR is validated for continuous duty with deionized (DI), reverse osmosis (RO), and ultrapure water streams meeting ASTM D5127, ISO 14644-1 Class 5 (ISO Class 5), and SEMI F63 standards for semiconductor-grade water. It exhibits no measurable extractables (tested per USP and EP 3.2.1) after 72-hour static exposure at 25°C. The assembly supports GLP/GMP-aligned installation qualification (IQ) and operational qualification (OQ) protocols, with pressure stability logs exportable for FDA 21 CFR Part 11-compliant audit trails when interfaced with Deepflow’s optional digital I/O module (CYMQ-DIO-01).
Software & Data Management
While the CYMQ000PR is a passive mechanical regulator, it is fully interoperable with Deepflow’s AquaControl™ SCADA platform (v4.2+). When paired with optional analog 4–20 mA pressure transducers (e.g., CYMQ-PT-02) and the CYMQ-DIO-01 interface, real-time inlet pressure data—alongside timestamped min/max/avg values and deviation alerts—is logged to encrypted SQLite databases. All records include electronic signatures, change history, and tamper-evident hashing, satisfying ALCOA+ principles for data integrity in regulated pharmaceutical and biotech laboratories.
Applications
- Stabilizing feed pressure to RO membranes in multi-stage UPW systems serving analytical labs (ICP-MS, LC-MS), cell culture facilities, and cleanroom wafer fabrication lines
- Mitigating hydraulic shock during pump start/stop cycles in central UPW distribution networks with looped recirculation
- Enabling reproducible performance of online TOC analyzers and particle counters requiring laminar, pulse-free flow profiles
- Serving as a calibration reference node in pressure cascade architectures where differential pressure across polishing cartridges must remain within ±0.01 MPa tolerance
- Supporting validation of water-for-injection (WFI) generation systems compliant with EU GMP Annex 1 and USP
FAQ
Is the CYMQ000PR suitable for use with hydrogen peroxide sanitization cycles?
Yes—the 316L stainless steel construction and fluorocarbon (FKM) diaphragm seals are rated for intermittent exposure to ≤3% H₂O₂ at ambient temperature per ASTM D471 testing.
Can this regulator be installed vertically or only horizontally?
It is certified for both orientations; however, vertical installation requires orientation-specific mounting brackets (included in CYMQ-MB-KIT) to prevent diaphragm sag-induced hysteresis.
Does the assembly include a relief valve for overpressure protection?
No—overpressure protection must be provided externally per ASME B31.9 and local plumbing codes; the CYMQ000PR is intended solely for regulation, not safety isolation.
What is the maximum allowable working temperature?
80°C continuous duty; short-term excursions to 95°C are permissible for up to 30 minutes during thermal sanitization protocols.
Is third-party certification available for semiconductor industry acceptance?
Yes—SEMI-certified test reports (SEMI F57-0221) and particle shedding data (≤1 particle ≥0.5 µm per 100 mL at 2 L/min) are provided upon request with purchase order confirmation.
