SH6000 Series

HDP High Pressure Double Guiding Parabolic Plug Type

Metal-seated quick-changeable trim combination with top and bottom guiding. This double guiding construction stabilizes stem and plug over the full travel range. The bottom guiding is located right below the seat ring and can be easily replaced. Most conventional body designs with top and bottom guided trim have a bolted bottom flange which requires an extra body gasket plus the risk of additional external leakage.

HDP is recommended for large pressure drop, high flow rate and instability fluids applications under high pressure conditions.
