Product catalog summary

Overview: The document provides comprehensive technical specifications and operational guidelines for various hydraulic valves, including directly operated relief valves, pilot-operated relief valves, solenoid valves, and sequence valves. These valves are designed to manage pressure and flow in hydraulic systems, ensuring protection against over-pressurization and efficient fluid control.

Specifications:

Operating Pressure: Ranges from 207BAR to 350BAR depending on the valve type.
Flow Rate: Varies significantly across models, from 0.4L/min to 1100L/min.
Temperature Range: -30°C to +120°C (-22°F to +250°F).
Internal Leakage: Maximum leakage rates vary, with some valves allowing up to 82ml/min.
Fluids: Suitable for mineral-based fluids with viscosities of 7.4 to 420 cSt.

Features:

Valves are constructed with hardened, precision-ground parts for durability.
Compact design and industry-standard cavities for ease of integration.
Fast response to pressure changes and low leakage design.
Adjustment mechanisms can be locked in place for stability.

Operation:

Relief valves open to allow flow to a tank when pressure exceeds a set value, protecting the system from over-pressurization.
Solenoid valves control fluid flow based on electrical signals, with options for normally open or closed configurations.
Sequence valves manage flow to secondary circuits once a set pressure is reached.

Adjustment and Materials:

Adjustment methods include screw and handwheel options.
Body materials include 6061-T6 aluminum and steel, rated at 207Bar and 350Bar respectively.
Seal kits available in Buna N and Viton.

Performance Curves: The document includes pressure drop vs. flow rate curves for each valve type, illustrating performance under different conditions.

Installation and Dimensions: Detailed installation dimensions and torque specifications are provided for proper setup and maintenance.

Ordering Information: The document outlines ordering codes for different valve configurations, including seal kits, body material, and porting options.

Obligations and Limitations:

Users must thoroughly read and understand all product documentation for safe installation and operation.
Meric products have specific application limitations and liability exclusions, particularly in high-risk environments.
