Modular Stack Valves

Product catalog summary

Overview: The PowrFlow™ Modular Stack Valves by Continental Hydraulics are engineered for high performance and reliability in demanding applications. They are available in various port sizes (D03, D05, D08) and offer functionalities such as check, flow control, relief, shuttle, and pressure reducing. Rated at 5000 PSI, these valves come with a three-year warranty.

Key Features:

High Pressure Rating: Rated at 5000 PSI at full flow.
Design: Patented floating cage design for self-alignment, advanced orifice design to prevent clogging, and black anodized bodies for durability.
Materials: Available in ductile iron or aluminum bodies.
Adjustments: Options include standard screw, tamper-proof cap, and hand-knob adjustments.

Specifications:

Flow: Nominal flow rates vary by valve type, with check valves supporting up to 20 GPM.
Temperature: Operates effectively up to 200°F, though temperatures above 130°F are not recommended for safety.
Filtration: 25 microns acceptable, 10 microns preferred.

Valve Types and Operations:

Check Valves: Allow free flow in one direction and block in the opposite. Available in direct and pilot-operated versions.
Flow Control Valves: Include pressure compensated and sub-plate mount options.
Pressure Control Valves: Include pressure relief, reducing, and sequence valves.

Ordering Information: Specific ordering codes are provided for each valve type based on size, style, and material.

Conclusion: PowrFlow™ Modular Stack Valves provide a comprehensive solution for hydraulic systems requiring reliable and high-performance components, ensuring long-term functionality and safety in various industrial applications.

Additional Specifications:

Valve bodies withstand pressures of 3000 PSI for aluminum and 5000 PSI for ductile iron.
Nominal flow rate is 60 GPM.
Pilot ratio is 3 to 1, with internal leakage limited to 5 drops per minute at 5000 PSI.
Compatible with general-purpose hydraulic fluids, requiring filtration of 25 microns, with 10 microns preferred.

Design and Ordering Information: Valves are available in modular stack designs with options for pilot-operated check valves and non-compensated flow control valves. Ordering codes specify valve type, size, style, control port, seals, and body material.

Flow Control Valves: Utilize a screw-in cartridge type, adjustable poppet design. They are non-compensated and feature zinc-plated external parts for durability. Flow rates vary from 10 GPM to 60 GPM depending on the model.

Features and Benefits: All external parts are zinc-plated for longevity. Valves are designed with industry-standard cavities and anodized aluminum for corrosion resistance. They are 100% functionally tested to ensure reliability.

Pressure Compensated Flow Control Valves: Maintain a constant flow rate regardless of system pressure or load changes, featuring reverse flow checks and adjustable settings.

Specifications:

Flow Range: 0.1 to 12 GPM nominal, with accuracy less than ±5% at a minimum of 200 PSI pressure differential.
Valve Bodies: Available in aluminum (3000 PSI) and ductile (5000 PSI) materials.
Operating Temperature: Fluid temperatures up to 200°F are acceptable, though temperatures above 130°F are not recommended for safety reasons.
Operating Media: Compatible with general-purpose hydraulic fluids.
Filtration: 25 microns acceptable; 10 microns preferred.

Operation: Valves maintain a constant flow rate regardless of system pressure or load changes. Reverse flow opens the check at 10 PSI, ensuring efficient operation under varying conditions.

Additional Features:

Anti-lunge assembly to prevent spool over-opening during initial activation.
Standard key lock assembly to prevent unauthorized tampering with valve settings.

Performance Charts: Includes typical pressure drop curves and flow path ΔP curves to illustrate valve performance under different conditions.

Valve Types:

Pressure Reducing Valve: Pilot operated, acts as a pressure regulating device for a secondary circuit.
Pressure Reducing/Relieving Valve: Similar to the reducing valve but also relieves pressure from the controlled port to the drain port.
Pressure Sequence Valve: Blocks flow until sufficient pressure is present, then opens to allow flow.

Additional Components:

Modular stack valve bolt kits with specifications for different NFPA standards.
