Features
• Compact structure with high cost-effectiveness.
• Instrument tubes can be easily installed by inserting transparent pipes and tightening nuts.
• The cut-off type liquid level gauge uses EPDM + PTFE sealing, while the diaphragm type liquid level gauge can use EPDM, FPM, PTFE, PFA, and F46 diaphragm materials.

Manufacturing Process
Step 1: Order and Design
Confirm customer requirements (size, pressure rating, connection type) and create technical drawings for the gauge valve, including material selection such as PVC, PP, or PVDF based on application.
Step 2: Raw Material Preparation & Molding
Select qualified plastic raw materials and perform injection molding or compression molding to form the main body and components of the gauge valve.
Step 3: Machining
Carry out precision machining on molded parts of the gauge valve, including thread processing, sealing surface finishing, and dimensional adjustment to ensure tight tolerance and smooth operation.
Step 4: Assembly
Assemble all components of the gauge valve, including valve body, diaphragm, bolts, and seals, ensuring proper alignment and torque control for leak-free performance.
Step 5: Testing & Quality Assurance
Conduct pressure testing, leakage testing, and functional inspection on each gauge valve to ensure it meets industry standards and customer specifications.
Step 6: Finishing, Packaging and Shipment
Clean the products, apply necessary labeling, and securely package the gauge valve to prevent damage during transportation before shipment.
