The API 602 Copper Gate Valve is a compact, forged valve engineered for reliable on-off flow control in low-pressure industrial pipelines, offering exceptional corrosion resistance and antimicrobial properties ideal for water, oil, gas, and potable systems. Conforming to API 602 standards for class 150-2500 forged steel valves, this Copper Gate Valve features a rising stem and solid wedge gate for clear visual indication of open/closed status, ensuring user-friendly operation and minimal flow impedance. With its robust copper alloy construction (B62), it withstands demanding environments in water management, chemical processing, and food & beverage industries, providing longevity and sanitation in critical applications.
Manufactured through precision forging, the Forged Gate Valve undergoes stringent heat treatment up to 1200°C and 100% chemical/mechanical testing per heat number, guaranteeing performance under pressures up to 1500LB and temperatures per ASME B16.34. The rising stem design (OS&Y) facilitates easy maintenance, while the bolted bonnet (BB) and full-bore (FB) structure minimize resistance for efficient flow. Available in sizes 1/4" to 4" (DN8 to DN100) with threaded (NPT), socket weld, or flanged ends, it supports diverse connections per ASME B16.5 or EN 1092. Nondestructive testing (RT, UT, PT, MT) and cryogenic treatment options (-196°C) ensure defect-free integrity, making it suitable for LNG or urea service.
The valve's copper alloy body and disc provide natural antimicrobial qualities, perfect for potable water systems where hygiene is paramount, while its Corrosion Resistant Gate Valve properties resist oxidation, acids, and salts in chemical or marine settings. The solid wedge gate ensures tight shutoff against bidirectional pressure, with optional Stellite overlays for abrasion resistance in slurries. Face-to-face dimensions comply with API 6D, ASME B16.10, or BS EN 558, enabling seamless integration into existing pipelines. Its low torque operation supports manual wheels or actuators, reducing operational costs in Low Pressure Gate Valve applications like municipal water distribution or steam lines.
Compared to cast valves, the API 602 Gate Valve offers superior compactness and leak-proof forging, with 3-5 times longer service life due to enhanced material integrity. Ideal for small-diameter pipelines requiring frequent isolation, it outperforms knife gates in clean media by minimizing turbulence (Cv up to 5,000). Custom options like pressure-seal bonnets for high-temp service or knife-edge wedges for fibrous flows enhance versatility. The valve's adherence to API 598 testing protocols confirms zero-leakage, ensuring safety in oil & gas or food processing where contamination risks are high.
Tackling challenges like corrosion in aggressive media, maintenance in tight spaces, and sanitation in water systems, this Copper Gate Valve delivers sustainable performance with minimal downtime. Its value-engineered pricing and robust design make it a cost-effective choice for engineers seeking reliable Forged Gate Valve solutions. Whether stopping flow in nitric acid lines or isolating potable water mains, the API 602 Copper Gate Valve provides unmatched durability, efficiency, and compliance for global industrial operations.
Engineered for reliable low-pressure isolation with corrosion-resistant copper and forged durability.
Gate valves have a simple design, widely used in low pressure-drop services. Their full-port design ensures unobstructed flow and no pressure drop, while also allowing pipeline cleaning with a pigging system.
A resilient seated gate valve with a non-rising spindle consists of the following parts. The body is the largest element of the valve, with the bonnet bolted for cleaning and maintenance. The wedge slides down to press the valve seat for complete shutoff and moves upward to allow flow. Over the last century, the construction has remained consistent, with improvements in service life, sealing performance, and corrosion resistance.
Modern gate valve bodies are more compact and sleek, enabling installation in limited space conditions while maintaining durability and efficiency.
Moves vertically to open or close, sealing against the seat for shutoff.
Made of ductile iron, it is the main housing that contains the fluid flow.
Ensures tight sealing when the wedge presses against it.
Transfers rotational motion to vertical movement of the wedge.
Supports the stem to reduce wear during operation.
Bolted to the body for easy cleaning and maintenance access.
Provides sealing around the stem to prevent leakage.
