Instrumentation valve TESCOM™ M5K

ballmanualisolation

Root isolation valves with outside screw and yoke, Features -True 4-bolt bonnet design provides easy access to the packing gland. Stem threads are completely isolated from the process. -Protective stem bellows and cap protects against atmospheric contamination, increases valve life and helps contain stem lubricant, reducing thread galling. -Compact design minimizes space requirements. Lower valve weight improves connection strength and reduces induced bending moments. -Multi-port outlet means fewer fittings, fewer leak points and reduced installation cost. -Standard CF8M investment cast yoke resists corrosion, increasing valve life. -Single-piece yoke design eliminates stem binding. -Widely compatible graphite or PTFE flange gasket ring minimizes bonnet-to-body gasket deterioration. -Free-swivelling ball end stem design (M5K, M5YK) or non-rotating plug design (M5AK) provide bubble-tight valve closure without metal seat galling and low seating torque. -Integral hard back seat (M5K, M5YK) protects against stem blowout and provides alternate sealing for longer packing life. -Optional replaceable soft seat design (M5K, M5AK) provides bubble-tight seat with a fully roddable, bi-directional flow.
