Technical Features
PMT Needle valves and Manifold valves are available in Pressure Ratings – 6000psi (Double Bonnet Design – 3000psi (Single Bonnet Design)
Non Rotataing Vee – which forms a bearing join with the stem eliminates rotation  between plug &seat at closure. This prevents scoring and galling up the valve seat and ensure long life in repetitive bubble tight shut off service.
Safely Bonnet Lock – Prevent accidental disassembly. Stem thread rolled & Hard Plated – Provaides additional strength & maximum service life Safely Back seating – Provides secondary stem seal in full open position, prevents stem blow out Body to Bonnet seal – Metal to Metal constant compression, Isolates bonnet threads from system fluids and eliminates possible tensile Dust cap – Prevents contamination and lubricant washout of bonnet assembly
PMT Valves Withstand 240 C Tem.
Packing : PTFE (Grafoil for temperature above 240 C to 550 C
