Liquid Ammonia Closed Sampler / Liquid Ammonia Hermetic Sampler

一．Product Introduction

The Liquid Ammonia Closed Sampler / Liquid Ammonia Hermetic Sampler (On-line Sampling Valve with Stainless Steel Safety Box) is equipped with a stainless steel safety box. It mainly consists of a valve body, valve core, valve stem, valve seat, safety box, and sampling bottle. The sampling bottle is detachable—after the sample enters, the matching bottle cap seals it to avoid contamination. The valve’s flow channel is designed with no retention or flow resistance, ensuring no impact on the pipeline flow rate. Rotating the handwheel drives the valve stem and core, which moves up and down to precisely control flow and sampling volume, guiding the sample into the bottle. Transparent and light-proof sampling bottles are available, and the valve is widely used in the pharmaceutical, chemical, and food industries.

二．Product Features

1. Enhanced Safety with Enclosure: Equipped with a stainless steel safety box for secure operation, minimizing risks of liquid ammonia leakage during sampling.
2. Hermetic & Contamination-Free: Detachable, sealable sampling bottles (transparent/light-proof) + retention-free flow channels prevent sample pollution and external contamination.
3. Precise Sampling Control: Handwheel-driven valve core (up-down lifting) enables accurate flow and volume adjustment, ensuring reliable sample collection.
4. Unobstructed Flow Design: Streamlined channels with zero flow resistance, avoiding interference with main pipeline flow.
5. Durable & Corrosion-Resistant: Multiple material options (304/316L stainless steel, fluorine-lined, Hastelloy, zirconium) suit harsh media like liquid ammonia.
6. Flexible Installation: Supports horizontal/vertical (optional) mounting and diverse connections (threads, welding, flange, clamp) for versatile setup.
7. Wide Industry Adaptability: Ideal for pharmaceutical, chemical, and food industries requiring safe, precise sampling of volatile or corrosive media.
