Description
TECHNICAL DATA SHEET
HYPLON LINED DIAPHRAGM VALVE (MANUAL HANDWHEEL)
Product: Hypalon Lined Diaphragm Valve (Straight-Through / Weir Type, Flanged)
Model/Series: SAVVY-G64X (as per product label imagery)
Date: October 30, 2026
1. PRODUCT DESCRIPTION
This manual diaphragm valve is engineered for reliable shut-off and throttling control of corrosive and abrasive fluids. It features a robust ASTM A395 Ductile Iron valve body, fully lined with Hypalon (Chlorosulfonated Polyethylene) to provide excellent chemical resistance against acids, alkalis, and oxidizing agents. The valve utilizes a manual handwheel operation, a rising stem design, and a straight-through flow path that ensures minimal pressure drop and prevents media accumulation. The durable Hypalon diaphragm effectively isolates the working mechanism from the media, ensuring long service life and bubble-tight sealing.

6. FEATURES & BENEFITS
-
Superior Chemical Resistance: The Hypalon lining is specifically resistant to oxidizing media, concentrated acids, bases, and chlorine solutions, outperforming natural rubber or EPDM in these aggressive environments .
-
Straight-Through Design: Provides unobstructed flow with minimal pressure drop and eliminates the “weir” pocket where solids can accumulate.
-
Bubble-Tight Shutoff: The flexible diaphragm seals tightly against the body lining, ensuring zero leakage (ISO 5208 Rate A) .
-
Isolated Working Parts: The diaphragm completely isolates the stem and bonnet mechanism from the line fluid, preventing corrosion and contamination.
-
Manual Rising Stem Handwheel: Provides clear visual indication of the valve position (open/closed) and allows for manual throttling.
-
Maintenance Friendly: Top-entry design allows for quick diaphragm replacement without removing the valve body from the pipeline .
7. APPLICATIONS
-
Chemical Processing: Sulfuric, hydrochloric, and nitric acid handling.
-
Water Treatment: Chlorination systems, sodium hypochlorite dosing, and brine solutions .
-
Mining & Minerals: Slurry and abrasive media transfer (benefiting from the straight-through path).
-
Pulp & Paper: Chlorine bleaching and stock preparation lines.
-
Pharmaceutical: High-purity fluid handling where contamination must be avoided.
8. TESTING & INSPECTION
-
Pressure Test: Each valve is hydrostatically tested for shell integrity and seat leakage in accordance with API 598 or ISO 5208.
-
Lining Inspection: 100% visual inspection and high-voltage spark test (holiday test) to ensure the Hypalon lining is free from pinholes, blisters, or discontinuities.
-
Diaphragm Test: Each diaphragm is inspected for fabric uniformity and molded dimensional accuracy.
