一、Product Overview
The Quantitative Sampling Valve Series is designed for applications requiring controlled and repeatable sampling. The valve adopts a 180° rotary opening and closing mechanism combined with a mechanical stop structure, enabling quantitative sampling under positive or negative pressure conditions.
The series is designed with a compact structure and reliable operation, making it suitable for industries with demanding requirements for hygiene, safety and sampling accuracy, including pharmaceutical, food, chemical, biological engineering and other applications.
The series includes Vertical Type, Customized Type, Well Type, Inner Lining of FEP Type and Cylinder Type configurations to accommodate different installation and sampling requirements.
二、Product Features
- Vacuum Compatibility: The valve can operate normally under vacuum conditions, helping prevent external contamination from entering the sampling system.
- Anti-Impact Design: The internal structure is designed to reduce material impact and minimize damage to the valve components during operation.
- Safety Positioning: A reliable mechanical positioning structure helps prevent safety risks caused by incorrect valve operation.
- 180° Rotary Operation: The valve opens and closes through 180° rotation, providing a defined operating position while reducing the space required for operation.
- Hygienic Design: Designed in accordance with GMP and FDA hygiene concepts, with a structure that facilitates cleaning and meets demanding hygienic operating requirements.
- Material Options: Valve body materials include 316L stainless steel, with PFA, PTFE and PEEK available for relevant components to meet requirements for corrosion resistance and chemical compatibility.
三、Working Principle
- Valve Closed: The valve core remains aligned with the sealing surface, keeping the sampling valve in the closed position.
- Rotary Preparation: Rotate the handwheel 180°. The valve core moves to the designated position, opening the sampling passage and allowing the medium to enter the sampling chamber under pressure.
- Quantitative Sampling: When the sampling chamber is filled, rotate the handwheel 180° in the opposite direction. The valve core returns to its original position, completing the quantitative isolation of the sample.
- Sample Collection: Open the sampling outlet and transfer the quantitatively collected medium into the sample container.
