VED*HL KD2

Product catalog summary

Overview: The VED*HL-*-KD2 series by Continental Hydraulics are valves designed for hazardous locations, compliant with ATEX 94/9/EC standards, suitable for explosive atmospheres classified under ATEX II 2GD for gas and dust.

Specifications: These valves feature a Zinc-Nickel surface treatment for enhanced corrosion resistance and are available in various sizes with maximum operating pressures of 5000 psi. They support 12V DC or 24V DC power supplies.

Performance: The valves have a hysteresis of less than 6% and repeatability within ±1.5% of Q max. Flow rates range from 20 gpm to 423 gpm, with response times varying by model.

Ordering and Options: Options include solenoids, ATEX approval, seal types, mechanical options, and spool types for specific flow characteristics.

Installation and Maintenance: Requires specific mounting surfaces and sealing rings, with options for piloting and drainage configurations.

Conclusion: The VED*HL-*-KD2 valves are robust, flexible solutions for hazardous environments, compliant with international safety standards.

Pressure Reducing Module: Protects valves from pilot pressures exceeding 3000 psi, with a fixed adjustment of 430 psi.

Hazardous Location Valves: Certified for explosive atmospheres with ATEX directives, featuring "Ex d" type protection.

Operating Temperature: Valves operate between -20°C to +80°C or -40°C to +80°C, classified in T4 temperature class.

Coil ATEX Classification: Suitable for gases, vapours, mists, and dusts, maintaining surface temperature limits.

Valve ATEX Classification: Suitable for ATEX II 2G or II 2D classifications for explosive atmospheres.

Solenoids and Wiring: Require appropriate fuses and grounding, with specific cable requirements.

Mounting Surfaces: Adhere to NFPA and ISO standards, with specified tolerances and bolt sizes.

Application Data: Designed for mineral oil-based fluids, with specific configurations to prevent leakage.

Specifications: Maximum pressure for aluminum subplates is 3000 psi, and for ductile subplates is 5000 psi.

Subplates and Seal Kits: Available in various sizes with Buna and Viton seal kits.

Valve Sizes: Available in sizes D03 to D10, each with specific valve codes.

About Continental Hydraulics: Known for durable, high-performance products since 1962, serving industries like food production and automotive.
