UNICON V100 unbalanced single-seat control valves and V200 balanced cage-guided control valves are mainstream regulating valve solutions designed for precise flow, pressure and temperature control in industrial process systems. Manufactured strictly per ASME B16.34 standard, the two series cover low, medium and ultra-high differential pressure working conditions, widely applied in petrochemical industry, thermal power plants, water treatment, HVAC, fine chemical, oil & gas industries.
The V100 single-seat valve features a simple unbalanced plug structure, excellent tight shut-off capacity and low overall cost. Without complicated balance components, this model realizes Class VI bubble-tight shutoff, perfectly meeting process requirements that need both regulation and emergency cut-off.
Best for systems with low differential pressure ≤3MPa
Simple internal structure, convenient on-site maintenance
Applicable media: water, common gas, conventional industrial oil
Ideal scenarios: water treatment pipelines, HVAC systems, low-pressure fine chemical production lines
V200 cage-guided balanced control valve adopts pressure balance structure on the top and bottom of the plug. The medium pressure counteracts each other, drastically lowering the thrust requirement of the pneumatic or electric actuator, avoiding valve vibration and instability under high differential pressure.
Adapt to full range differential pressure, maximum differential pressure up to 16MPa
Cage guiding structure improves centering performance, reducing plug abrasion
Matched with multi-hole noise reduction cage, multi-stage anti-cavitation cage and disc stack trim
Main application: power plant steam regulation, petrochemical high-pressure process pipelines, high-pressure natural gas pipelines
A core advantage of UNICON V100 & V200 control valves is the quick-change trim design. No welding or locking screws are arranged inside the valve body and bonnet, so users can replace inner trim without detaching the whole valve from the pipeline, greatly shortening maintenance downtime. Optional trim types include:
Contoured P-Port Trim: Universal plug for most liquid, steam and gas regulation, stable flow control
V-Notch Micro Flow Trim: Realize ultra-precise tiny flow adjustment for pharmaceutical batching and micro ingredient adding
Multi-step Anti-Cavitation Trim: Split pressure step by step to eliminate cavitation erosion on valve core
Multi-Hole Low Noise Cage: Disperse high-speed airflow to lower running noise of steam/gas valves
Disc Stack Trim: Custom multi-layer disc structure for extreme high differential pressure working conditions, combined with CFD simulation optimization to resist cavitation and abrasion.
Design Standard: ASME B16.34
Nominal Size: V100 DN15~DN150; V200 DN40~DN800
Pressure Class: Class 150, 300, 600, 900, 1500
End Connection: RF flange, butt weld, NPT thread optional
Body Material: WCB carbon steel, WC6 alloy steel, CF8/CF8M stainless steel, Hastelloy, Monel for anti-corrosion demand
Actuator Matches: Pneumatic diaphragm actuator, pneumatic cylinder actuator, electric actuator, hydraulic actuator
Protection Grade: IP65, support outdoor installation
Wide applicability: one valve platform matches multiple trims to cope with cavitation, noise, micro-flow, high-pressure differentials and other complex working conditions
Low maintenance cost: quick-change trim design cuts maintenance time by more than 60% compared with traditional control valves
Stable service life: precision casting valve body + hardened trim material, normal service life reaches 8–15 years
Environmental protection upgrade: low-emission packing can realize zero fugitive emission, satisfying environmental protection production standards
Complete certification: CE, ISO9001 certified, conforming to international industrial procurement norms.
Warranty period: 12 months from the date of shipment
Lifelong supply of spare trim, seals and wearing parts
Remote technical guidance for installation, commissioning and fault troubleshooting
Custom service: customized material, trim structure and special connection size according to working condition parameters
Export packaging: standard plywood fumigation-free export wooden case to avoid damage during ocean transportation.
