Design Features

(1) Double "D" stem head which ensures handle lever will always be mounted correctly, parallel to flow, indicating valve open and closed positions. (2) Secure line flow locking device: the valve is equipped with an integral locking device to secure line flow. (3) Anti-static device: Spring loaded pins assures that the electrical continuity between the ball, stem and body, to avoid arcing due to static buildup. (4) Blow-out proof stem: the lower end of the separate stem is T-shoulder shaped to create an integral collar making the stem blow-out proof. (5) Bolted body maintains seal integrity with properly torqued bolting. (6) Fire safe design: metal to metal sealing shuts off valve flow when soft sealing materials are destroyed by fire.
