Pneumatic Stainless Steel Quantitative Sampling Valve

一．Product Introduction

The Pneumatic Fluorine-Lined Quantitative Sampling Valve adopts an all-fluorine-lined design, suitable for sampling under corrosive working conditions and solving the problem of high cost of special materials. It mainly consists of a fluorine-lined valve body, fluorine-lined valve core, fluorine-lined valve stem, valve seat, pneumatic actuator, and sampling bottle. The sampling bottle is detachable—after the sample enters the bottle, it can be sealed to avoid contamination. The flow channel is designed with no flow resistance, which does not affect the flow rate. The valve stem is rotated by a handle, electric actuator, or pneumatic actuator to drive the valve stem and valve core, allowing the sample to enter the valve core. Rotating the valve core 180° enables the sample to flow into the sampling bottle; during sample discharge, the valve core closes the sampling port to achieve zero leakage and pressure-free sampling. This design prevents pressure impact on the sampling bottle caused by valve switching, ensuring operator safety. The sampling bottle is available in transparent and light-proof types, and the valve is widely used in the pharmaceutical, chemical, and food industries.

二．Product Features

1. Precise quantification: Stable pneumatic actuation ensures consistent sampling volume, no manual errors.
2. Corrosion resistance: 304/316L stainless steel adapts to harsh media (acids, alkalis, organic solvents).
3. Safe & efficient operation: Pneumatic control enables remote/automatic use, no direct medium contact.
4. Reliable sealing: Dual-seal structure (O-ring + packing) prevents leakage and cross-contamination.
5. Flexible adaptation: Multiple installation/connection methods, compatible with GB/ANSI standards.
