Globe Valve Types
We offer a comprehensive range of globe valves for various industrial applications:
Standard Pattern Globe Valve
Most widely used design — straight-flow configuration for reliable shut-off and throttling. Suitable for water, steam, compressed air, cooling water, and chemical pipelines. Advantages: reliable sealing, easy maintenance, long life, cost-effective.
Y Pattern Globe Valve
Straighter flow path reduces pressure drop and turbulence. Ideal for high-pressure steam, power plants, refineries, and petrochemical plants. Benefits: lower pressure drop, higher efficiency, longer seat life.
Angle Globe Valve
Changes flow direction by 90° — eliminates additional fittings. Used in boiler systems, drain lines, condensate, and high-pressure discharge. Advantages: compact, lower cost, easier maintenance.
Key Features & Benefits
Precise Flow Regulation: Optimized disc and seat geometry enables accurate throttling — ideal for systems requiring continuous flow adjustment, not just on/off operation.
Excellent Shut-Off Performance: Precision-machined seats ensure tight sealing at low and high pressures. Options: metal-to-metal, Stellite hard-faced, or soft sealing — minimizing leakage and improving system safety.
Outstanding High-Temperature Performance: Suitable from cryogenic up to 650°C — depending on materials. Applications: superheated steam, thermal oil, boiler systems, refinery pipelines.
Superior Pressure Resistance: Heavy-duty construction enables reliable operation under demanding conditions. Pressure classes: PN16–PN420, ANSI Class 150–2500. Suitable for steam, oil/gas, petrochemical, and power plants.
Long Service Life:High-quality materials, optimized surfaces, and strict tolerances reduce wear — lowering maintenance frequency, downtime, and lifecycle costs.
Wide Material Options:Bodies: Carbon steel, cast steel, stainless steel, duplex, alloy steel, chrome-moly. Seats: Stainless steel, Stellite, hardened alloy. Stems: SS410, SS420, SS304, SS316, F6a, duplex. Engineering recommendations based on media, temperature, pressure, and corrosion.
Automation Ready: Equipped with handwheel, gear operator, electric/pneumatic actuators, positioners, limit switches, solenoid valves, and position feedback — seamless integration into automated control systems.
International Engineering Compatibility: Manufactured to API, ANSI, ASME, DIN, EN, ISO, BS, JIS, GB standards — reducing complexity for EPC contractors and global procurement teams.
Material Selection Guide
Selecting the appropriate valve material is critical to ensuring long-term reliability, corrosion resistance, and safe operation. Our engineering team helps customers select the optimal material combination based on media characteristics, operating temperature, pressure, and project requirements.

Manufacturing Process
Every Zhengmao globe valve is manufactured through a standardized production process designed to ensure dimensional accuracy, structural integrity, and long-term operational reliability.
Raw Material Inspection: Material certificates, chemical composition, mechanical properties, dimensions, and surface quality are verified before production.
Casting or Forging: Precision casting or closed-die forging ensures excellent mechanical strength, stable structure, consistent dimensions, and reliable pressure-bearing performance.
CNC Precision Machining: Critical components are machined — body cavity, seat surface, stem, disc, flange drilling, thread processing, and face-to-face dimensions — ensuring smooth operation and reliable sealing.
Component Assembly: Experienced technicians assemble body, bonnet, disc, stem, seat, packing, gaskets, and fasteners per standardized procedures. Each stage is documented.
Pressure & Functional Testing: Every valve undergoes hydrostatic shell test, seat leakage test, air leakage test, torque test, cycle test, and visual inspection — only approved units proceed.
Surface Protection: Epoxy coating, anti-corrosion painting, rust prevention, or stainless steel finishing — applied per customer specifications.
Final Inspection & Export Packaging: Product ID, dimensions, pressure rating, material marking, coating quality, packaging, labeling, and shipping docs are verified — ensuring readiness for installation.
