QUALITY FEATURES HIGH PERFORMANCE VALVE HP 111 STR AIGHT THROUGH SH A F T ensures maximum bending strength. M AINTE N A NCE - FR E E BE A RING For all nominal diameters maintenancefree, overlong corrosion and temperature-resistant bearings are used for exact centring of the valve discs. INCONE L SE AT RING FORCE - LOCK E D CONNEC TION between disc and shaft. Low shear stresses thanks to tangentially arranged tapered pins. The Inconel seat ring guarantees a b s o lute t i g ht n e s s and compensates for wear. The seat ring can be replaced without disassembling the shaft and valve disc. Alternative: R-PTFE or Fire-safe VA LV E DISC The valve disc has a double eccentric bearing design, resulting in low torques and low wear. All sealing surfaces are machined. CL A M PING RING protects the seat ring from abrasion and erosion.
