Inlet/Outlet Valve: Temperature Range -20°C to 150°C

Q: How does this valve differ from standard shut-off valves?

It features rapid actuation, higher cycle durability (>1 million cycles), and precision sealing for metering accuracy, unlike general-purpose valves designed for isolation only.

Component Specifications

Definition

A specialized valve component integrated into metering devices that precisely regulates the inlet and outlet flow of liquids, gases, or semi-solids. It ensures controlled material transfer during measurement cycles, maintaining accuracy and repeatability in industrial dispensing applications. The valve operates through mechanical, pneumatic, or electrical actuation to open/close flow paths with minimal pressure drop and contamination risk.

Working Principle

Operates via actuator-driven mechanism (e.g., solenoid, pneumatic piston) that moves a sealing element (ball, diaphragm, or poppet) to open/close flow channels. In metering applications, it synchronizes with measurement cycles—opening to allow material entry into the metering chamber, closing during measurement, and reopening for controlled discharge. Precision is achieved through tight tolerances and rapid response times.

Materials

Body: 316L stainless steel (corrosion-resistant); Seals: PTFE or FKM (FDA-compliant for food/chemical); Actuator: Anodized aluminum; Spring: Inconel (high-cycle fatigue resistance).
