Product Features:

1.Space-Saving Non-Rising Stem  

Stem rotates internally without vertical movement, reducing installation height by 40% vs. rising stem designs – ideal for low-clearance valve chambers or underground pits.  

Torque optimization: Precision-machined trapezoidal threads cut operating force to ≤240 Nm, enabling single-operator handling even at DN300 sizes.  

2. Bubble-Tight Resilient Seating  

Full-rubber encapsulated wedge (EPDM/NBR) compresses against ductile iron body for zero-leakage shutoff .  

Abrasion-resistant design: Reinforced rubber-to-metal bonding withstands 50,000+ cycles in sandy water.    

3. Corrosion & Chemical Defense  

Body/Wedge: 250µm fusion-bonded epoxy coating (RAL 5005 blue) for chlorine/UV resistance.  

Stem: Stainless steel with PTFE-packed gland, preventing grit ingress in wastewater.  

4. BS5163 Compliance & Global Certifications  

Manufactured to BS5163 standards, with additional certifications: CE , ACS, WRAS, UKCA,and ISO9001 quality management.  

5. Low Lifecycle Costs

Maintenance-free bushings: Self-lubricating RPTFE stem guides eliminate greasing needs.
