MTV Stack-type Throttle Valve Technical Specification & Application Overview
Core Definition & Structural Features
• Type Classification: Hydraulic stack-type throttle valve adhering to ISO 4401 standards, designed for modular integration into hydraulic manifolds. Features bidirectional flow control: forward flow enables stepless flow adjustment (e.g., 0.3–6.5 L/min) via rotary knob, while reverse flow activates an integrated check valve for rapid unrestricted flow.
• Material & Manufacturing: Valve body constructed from high-strength alloy steel or hardened materials. Precision-ground components (e.g., conical throttle spool) paired with corrosion-resistant seals ensure reliability under high pressure (21 MPa) and extended temperature ranges (-20°C to 80°C).
Technical Parameters & Performance Metrics
• Representative Models:
• MTV-02P/03P Series: Operates at 21 MPa pressure with flow regulation range of 0.2–15 L/min (hydraulic oil medium). Compatible with mineral oils, water-glycol, and phosphate esters.
• MTCV-02W: Nominal port diameter 10 mm, maximum flow 15 L/min, adjustment ratio ≥10:1. Reverse flow check valve opens at ≤0.08 MPa.
• Key Performance Attributes:
• Flow Stability: Precision-machined orifices and wear-resistant materials ensure smooth flow-pressure differential characteristics with minimal pulsation.
• Adjustment Precision: Clear calibration markings with locking nuts prevent parameter drift under vibration. Low torque adjustment mechanism enables sensitive control.
• Environmental Robustness: High-impact alloy body with full-flow channel design minimizes pressure drop (<0.2 MPa), enhancing system energy efficiency.
Application Scenarios & Industry Cases
• Industrial Applications:
• Construction Machinery: Hoist control in cranes, actuator speed regulation in excavators.
• Machine Tools: Feed rate control in CNC systems, cylinder cushioning in machining centers.
• Plastics Processing: Injection molding machine mold opening/closing speed control, cooling system flow regulation.
• Metallurgy: Pressure stabilization in rolling mills, hydraulic cylinder motion control in continuous casting machines.
• Specialized Systems:
• Integrated with relief valves for flow-controlled speed regulation circuits (inlet, outlet, or bypass throttling), suitable for medium-speed stability requirements under varying loads.
• Paired with capillary tubes in HVAC/R systems for refrigerant flow control during heating/cooling modes.
