The valve consists of a fully welded body and a carbon-reinforced PTFE sealing seat, designed for frequent operation in complex and chemically aggressive environments. The precision-ground stainless steel ball ensures long-term reliable service with consistent sealing performance over years of operation.
A floating ball design is employed, with a beveled spring washer ensuring that the seal ring is always tightly pressed against the ball. This maintains tight shut-off even under fluctuating pressure conditions.
To prevent stem leakage, the valve features a dual O-ring sealing structure around the stem, ensuring smooth rotation while maintaining a secure, leak-proof seal.
— Maintenance-free, self-adjusting, and low-friction design makes installation easy and ensures long-term, reliable performance with minimal operating cost.
— The operating handle is detachable and reversible for flexible installation.
— The valve body contains no heavy or unreliable cast components.
— Simple installation and adjustment mechanism for quick commissioning.
— Optional extended stem design facilitates insulation in buried or elevated applications.
