Manual PFA-Lined Sampling Valve

一．Product Introduction

The Manual PFA-Lined Sampling Valve (Corrosion-Resistant 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 corrosion-resistant 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. Excellent Corrosion Resistance: All-fluorine-lined (PFA/F46) design adapts to corrosive media, avoiding high-cost special materials.
2. Zero Leakage & Safe Sampling: 180° core rotation enables pressure-free sampling with closed port during discharge, ensuring safety.
3. Contamination-Free: Detachable sealed bottles (transparent/light-proof) + retention-free flow channels prevent cross-contamination.
4. Unobstructed Flow: Streamlined channel design without affecting main pipeline flow.
5. Flexible Adaptation: Supports manual/pneumatic/electric actuation; horizontal/vertical installation + multiple connections.
6. Durable: Stainless steel (304/316L)/titanium body + PTFE/PPL seats for harsh conditions.
7. Wide Application: Suitable for pharmaceutical, chemical, food industries.
