Keystone Model OptiSeal F14F17 Butterfly Valves
006486-HW-KEYSTONE-086
Overview
The valve features a top bushing designed to absorb actuator side thrust loads, ensuring smooth operation and prolonging the valve’s service life. Its actuator flange is built according to ISO 5211 standards, making it compatible with a wide range of actuators. Additionally, the valve's high-solids, glossy, silicone-free paint system offers superior corrosion resistance, making it ideal for harsh environments.

The valve seat is field-replaceable and provides full isolation between the body and stem from the flow, ensuring safety and durability in various operating conditions. The primary stem sealing exceeds the valve's pressure rating, offering enhanced leakage prevention, while a secondary shaft sealing acts as a backup for added safety. Notably, no flange gaskets are required, further simplifying installation and maintenance.
