OPERATION NOTES AND WARNINGS: The SkoFlo valve has hard seats and is not designed to provide complete "bubble-tight" shut off. Separate isolation valves should be used for shutting off the flow. Overtightening the handle could cause damage to the stem section. If flow rate does not decrease when turning the handle in, see "Trouble Shooting Improper Valve Performance". - Page 6 Unscrew and remove the base cap. Screw a bolt into the thread on the piston (use handle retainer lock bolt or any M8 bolt) and carefully pull out the piston assembly and the springs. (See Figure II). Figure II If replacing the seal on the ceramic seat, remove the snap ring and seat retainer.
