1. Model Breakdown & Naming Convention
PTS1-16-0-160is decoded as follows:
• PTS1: Series code (e.g.,Pressure ControlorProportional Throttleseries; verify via Danfoss catalog).
• 16:
• Port Size: 16mm (SAE 6/ISO 06 standard).
• ORPressure Rating: 16MPa (confirm with series).
• 0:
• Function Code: Standard configuration (e.g., no special features).
• ORSpring Setting: Default preload (e.g., "0" = no preload).
• 160:
• Max Pressure: 160bar (16MPa).
• ORFlow Coefficient: Cv=1.60 (verify).
Recommendation: Cross-reference with Danfoss’s officialCartridge Valves Catalogfor precise naming rules.

2. Core Functions & Technical Features
Possible Function Types(based on series):
• Pressure Control Valve:
• E.g., Pressure Reducing, Sequence, or Counterbalance Valve.
• Key Feature: Controls outlet pressure via spring-oil pressure balance to prevent system overload.
• Proportional Throttle Valve:
• E.g., Electro-Hydraulic Proportional Flow Control Valve.
• Key Feature: Stepless flow adjustment via electrical signals (current/voltage) for precision control.
General Technical Advantages:
• Compact Design: Cartridge-style for direct valve block integration, saving space.
• High Reliability: Hardened steel spool with wear/corrosion resistance.
• Modularity: Combines with other Danfoss valves (e.g., directional + pressure valves).
• Low Leakage: Poppet design with ≤0.1mL/min leakage (typical).
