This page explains how Valve Mechanism is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A mechanical or electromechanical device within filling nozzles that controls the flow of liquids or gases by opening, closing, or partially obstructing passageways.
Technical details and manufacturing context for Valve Mechanism
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Nominal Diameter | 15–100 mm | Determines flow capacity and connection size.ISO 6708 |
| Operating Pressure | 1.0–1.6 MPa | Below 1.0 MPa the seat load is insufficient. |
| Operating Temperature | -40–85 °C | Outside range seals may fail. |
| Flow Coefficient | 2.5–120 Cv | Indicates flow capacity at given pressure drop.ISO 6358 |
| Leakage Rate | ≤0.01 % | Class VI shutoff; higher leakage indicates wear.ISO 5208 |
| Actuation Time | 0.5–2.0 s | Full stroke open/close; critical for process control. |
| Supply Voltage | 24 ±10% V DC | For electromechanical actuators.IEC 60038 |
| Power Consumption | 5–20 W | Steady-state; peak may be higher during actuation. |
| Ingress Protection | IP54–IP65 | Higher rating for washdown environments.IEC 60529 |
| Body Material | 316L | Corrosion resistance for food and chemical service.ASTM A240 |
| Seal Material | PTFE | Chemical compatibility and temperature rating.ASTM D4894 |
| Weight | 2.5–15 kg | Affects mounting and handling. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The directory reference range for operating pressure is 1.0 to 1.6 MPa. Above 1.6 MPa, seals may fail. Always confirm the exact rating for your specific model with the manufacturer.
The body material is typically 316L stainless steel, and the seal material is PTFE. These materials offer corrosion resistance for food and chemical service. Verify compatibility with your media and temperature requirements.
The mechanism moves a sealing element relative to a seat to open or close the flow path. Some designs allow proportional control to regulate flow rates. Actuation is via pneumatic, hydraulic, or electric actuators, and the actuation time is critical for process control.
Signs of wear include increased leakage rate (above 0.01%), longer actuation times, or visible damage to sealing surfaces. Regular inspection and replacement of seals may be necessary. Always follow the manufacturer's maintenance guidelines.
