Jordan Valve & LowFlow - Fluid Control Valves

Technologies

• Jordan Valve: sliding gate control valves and pressure/temperature regulators engineered for stable control, low wear, and tight shutoff.
• LowFlow (by Jordan): compact, precision control valves for pilot plants, sampling skids, and specialty chemical dosing where fine Cv resolution and repeatability are critical.

Common chemical applications

• Reactor temperature and pressure control (steam, thermal fluids, cooling water, nitrogen purge)
• Feed dosing of monomers, catalysts, inhibitors, pH/neutralisation chemicals
• Utility control (steam conditioning, condensate return, plant air, nitrogen)
• Pilot plant/process development where small line sizes and high rangeability are required
• Corrosive service using compatible materials and trim options

Key benefits

• Accurate modulating control with sliding gate technology → stable product quality and fewer off spec batches
• High rangeability to cover start up, turndown, and normal operation in one device
• Erosion resistance and low cavitation risk, supporting longer life in abrasive or flashing services
• Compact footprints (especially LowFlow) → smaller panels and skids
• Broad Cv/trim and material options to match media and process conditions

Equilibar – Back Pressure Regulators (IC & BD Series)

Technologies

Equilibar BPRs use a multi orifice diaphragm architecture piloted by a stable reference signal to deliver exceptionally fast, precise back pressure regulation. They maintain setpoint across very low to very high flow, manage two phase and viscous streams, and tolerate particulates better than traditional needle seat BPRs.

IC Series – Industrial Control

• Designed for industrial chemical service, available in chemically resistant wetted materials (e.g., 316L SS, Hastelloy alloys – model dependent)
• NPT/flanged connectivity and broad Cv ranges for plant integration
• Excellent for reactor back pressure, membrane/permeate control, filter protection, and vent/flare regulation

BD Series – Broad duty/High demand service

• Targets demanding pressure/temperature envelopes and challenging media (model dependent)
• Well suited to continuous processes, two phase flow, slurry handling, and high turndown R&D/pilot workflows
• Common in supercritical CO₂ extraction, catalyst screening, polymerisation, and distillation bottoms control

Common chemical applications

• Reactor pressure control for equilibrium, selectivity, and yield
• Filtration/UF/NF/RO permeate control, preventing membrane damage and improving flux stability
• Gas liquid or two phase lines where conventional BPRs hunt or clog
• Pump pulsing dampening and syringe pump regulation in labs and pilot lines

Key benefits

• Ultra stable upstream pressure across wide flow regimes → consistent reaction kinetics
• Handles challenging media (viscous, two phase, particulate laden) → better uptime
• Fast dynamic response → reduced oscillation and tighter control windows
• Material/configuration flexibility to match corrosives and temperature extremes

Alicat – Flow Measurement & Control (DP & Coriolis)

Technologies

• Differential pressure (DP) laminar flow devices (Alicat M and Alicat MC ranges) use dP and temperature sensing through a laminar element to deliver fast response (ms level) and high repeatability.
• Coriolis devices provide true mass flow independent of fluid properties—ideal for unknown gas mixes, liquids, and wet gases.

Focus models for chemical compatibility & hazardous areas

• Alicat MCS (stainless wetted variants of meters/controllers) → higher chemical compatibility with corrosive gases/liquids
• IS Range (intrinsically safe variants, approvals model dependent) → use in hazardous areas with appropriate certifications (e.g., ATEX/IECEx/UKEX as applicable)

Common chemical applications

• Gas dosing (H₂, N₂, CO₂, Cl₂ derivatives, acid gases—check compatibility), blanketing, purging
• Additive/catalyst feed control and mass balance tracking
• Solvent and monomer flow (Coriolis for liquids/unknown properties)
• R&D and pilot plant where rapid setpoint changes and multi gas capability are valuable

Key benefits

• Fast control and tight repeatability → improved batch consistency and reduced cycle time
• Multi gas configurability (DP) and property independent accuracy (Coriolis) → flexibility across campaigns
• Stainless wetted paths (MS/MCS) → enhanced corrosion resistance
• Intrinsically Safe options → deploy in classified zones (verify specific approval per model)

Alicat – Pressure Control (Single & Dual Valve)

Technologies

• Single valve pressure controllers (Alicat PCS/PCRS): regulate by throttling inlet (or exhaust, model dependent) to hold a setpoint.
• Dual valve pressure controllers (Alicat PCDS/PCRDS): actively manage inlet and exhaust for faster settling and bidirectional correction—ideal where supply/exhaust conditions vary.
• Alicat PC series: pressure sensors/meters for accurate measurement feeding PLC/DCS loops or QA.

Focus ranges for chemical service

• PCS / PCRS (single valve) and PCDS / PCRDS (dual valve): “S” stainless wetted paths → higher chemical compatibility
• IS variants: intrinsically safe models for hazardous areas (certifications model dependent)

Common chemical applications

• Reactor jacket and headspace control (keep pressure windows tight under exotherms)
• Membrane and filter testing (maintain transmembrane pressure)
• Leak/pressure decay test stands
• Distillation column pressure control to stabilise relative volatility
• Blanket pressure on tanks and day vessels

Key benefits

• Fast, stable pressure with low overshoot → better safety margins and reproducibility
• Dual valve authority in dynamic processes reduces hunting and downtime
• Stainless wetted paths for corrosive duty; IS options for zoning compliance
• Native analog/digital communications facilitate PLC/DCS integration

Drastar – Pressure Regulators

Technologies

Drastar manufactures single stage, dual stage, dome loaded, and back pressure regulators for gases and liquids. Known for stable setpoint, low droop, and wide pressure ranges, with 316L stainless and other corrosion resistant materials available (model dependent).

Common chemical applications

• Specialty & corrosive gas primary/secondary pressure reduction (cylinders to tool pressure)
• Analyzer/sample conditioning skids and purge panels
• High pressure testing and reactor feed conditioning
• Pilot plant utilities where compact, reliable regulation is essential

Key benefits

• Consistent outlet pressure across changing demand → protects instruments and reactors
• Clean, corrosion resistant builds (316L, optional alloys) → longer service life
• Compact layouts for panels and skids
• Options for high pressure/temperature envelopes (model specific)
