Series M4 Severe Service Ball Valve

Engineered specifically for vent and drain isolation applications within the power industry. Rigorously tested for dependable, zero leakage performance in high pressure and high temperature steam applications.

Series M4 Severe Service Ball Valve

Rigid One-Piece Body Construction

One-pieced forged body for added rigidity and elimination of leak paths associated with body joints. Robust, heavy walled body construction contains an external groove for conductive heat dissipation during the post weld heat treatment process.

Series M4 Severe Service Ball Valve

Bubble-Tight Seat Sealing

Utilizes same material and coating composition for ball and seat to maintain a reliable, tight shut off during thermal cycling over the life of the valve. The ball and seat are 360° mate lapped to create a truly spherical interface. The seat’s wide seal band reduces dynamic cycling stresses, promoting extended service life.

Series M4 Severe Service Ball Valve

Advanced Coating Technology

Application specific advanced wear coatings are applied to the ball and seat for enhanced erosion and corrosion resistance, resulting in extended service life.

Series M4 Severe Service Ball Valve

High-Strength Drive Train

Utilizes a one-piece, high-strength, blowout proof stem design with an upper bearing ring to ensure proper stem alignment, maximizing the stem seal life by limiting side loading.

Series M4 Severe Service Ball Valve

Robust Actuator Mounting Bracket

One-piece, robust cast steel actuator mounting bracket is securely attached to the body for superior rigidity. The mounting bracket and the body stem bore are CNC machined for precise alignment to eliminate side-to-side motion of the stem. The mounting bracket is machined per ISO 5211 for direct mounting.
