Overview

This technical document provides comprehensive specifications, configurations, and ordering information for Lynch hydraulic bar manifolds and valve packs, focusing primarily on D03, D05, D07, D08, and D10 series. It covers manifold materials, valve patterns, circuit types, porting standards, mounting options, relief cavities, pilot port configurations, spacing dimensions, and accessories.

1. Product Features and Materials

• Manifolds are manufactured mainly from Aluminum (lightweight, high flow) and Ductile Iron (durable, heavier), with optional Mild Steel and Stainless Steel.
• Consistent manifold layouts regardless of port codes; flange ports available with UNC or Metric mounting threads.
• Four-bolt mounting options enhance vertical installation stability, especially for D03 and D05 standard flow parallel manifolds.
• Common drain ports on both ends facilitate manifold series connections without extra fittings.
• Independent pilot pressure ports are standard; common pilot pressure ports optional on high and very high flow manifolds.
• Dual tank ports standard on high flow D05H and D05HE manifolds for compatibility with competitor products.
• Port isolations for pressure (P) and tank (T) ports available up to 10 stations, with additional gauge ports when feasible.

2. Non-Standard Options and Accessories

• Single station manifolds may lack gauge ports due to size constraints; special models with gauge ports are available.
• Manifolds can be supplied with work ports one size smaller than standard.
• Bottom ported manifolds offered for D03 and D05 sizes.
• Special manifolds with dual work ports and oversized interface ports support high-performance proportional valves.
• Four or six bolt mounting options for vertical or tank top installations.
• D05 high flow and very high flow manifolds can include "L" port options.
• Two-station valve adapters for two-speed functions standard for D03 through D08 sizes.
• Many series available in all-metric formats with standard metric dimensions and materials.

3. Part Numbering System and Product Index

The part numbering system encodes manifold type (Bar Manifold), material (Aluminum or Ductile Iron), valve pattern (standard, high flow, very high flow, series circuit), circuit type, capacity, spacing, number of stations, port code (SAE, NPT, BSP, Metric), mounting threads, relief cavity options, and pilot port configurations.

Manifold models are categorized by size (D02, D03, D05, D07, D08, D10), flow capacity, circuit type (parallel, series), porting style (SAE flange, bottom ported), and special features (X & Y ports, pilot port adapters).

4. Technical Specifications and Dimensions

• Station counts range from 1 to 16 depending on model.
• Spacing options vary: 1.63", 2.13", 2.125", 3.25", 4.00", 5.00", 5.25", 7.00", and 9.00" depending on series and flow capacity.
• Manifold lengths (Dim. "L") scale with station count and spacing, critical for installation planning.
• Weight estimates provided for aluminum and ductile iron versions, with iron significantly heavier.
• Relief cavities and gauge ports are optional, typically available on special order; single station manifolds generally exclude gauge ports.
• Examples include D03 high flow parallel circuit manifolds with 2.13" spacing, D05 standard and high flow manifolds with 3.25" and 5.00" spacing, and D07/D08 series with larger spacing and flow capacities.

5. Isolation Port Codes and Relief Valve Options

• Isolation port codes define configurations for pressure (P) and tank (T) port isolations between stations, enhancing hydraulic circuit customization.
• Relief valve locations and standard relief codes are detailed, supporting various relief cavity options including Sun T-3A, Sun T-10A, and C10-2.
• Relief valves cover capacities from 12 to 200 GPM with pressure ranges from 50 to 6000 psi, featuring Buna-N or Viton seals and multiple adjustment types (standard screw, tamper-resistant, handknob).

6. Valve Patterns and Circuit Types

• Valve patterns include 05G (single tank gallery, no pilot ports), 05T (dual tank galleries, no pilot ports), 05H and 05E (dual tank galleries with pilot ports).
• Circuit types cover parallel (standard, high, very high flow) and series circuits, with options for independent or common pilot ports (X & Y).

7. Porting and Mounting Threads

• Port codes support SAE, NPT, BSP, BSPP, BSPT, and Metric standards with detailed thread sizes and depths.
• Mounting threads include UNC and Metric options with specified pitch and depth, ensuring compatibility with various valves and system components.

8. Accessories and Custom Options

• Available accessories include tapping plates, valve adapters, subplates with circuits, cover plates, headers/junctions, and DIN bodies.
• Special order options include shaded area configurations, additional pilot port adapters, wide spacing, and optimized construction methods to reduce installation complexity.

9. Critical Information and Best Practices

• Select manifold material based on application requirements balancing strength, corrosion resistance, and weight.
• Four-bolt mounting improves manifold stability and performance in vertical installations.
• Common drain and pilot ports simplify manifold series connections and pilot pressure management.
• Non-standard options enable customization for specialized hydraulic functions, including two-speed valve adapters and metric configurations.
• Verify porting standards and mounting thread compatibility with valves and system components.
• Consult factory for availability of special models, mounting adapters, non-standard porting, and relief cavity options.
