CENTRIC WAFER BODY BUTTERFLY VALVE FEATURES
  • STEM Precision double "D" disc to stem I connection drives the disc without the need for screws or pins. The close tolerance, double "D" connection that drives the valve disc is an exclusive feature of the OMVAL. Disassembly of the Pascal stem is just a matter of pulling the stem out of the disc.
  • STEM RETAINING : The stem is retained in the body by means of a unique stainless steel Spirolox retaining ring, manufactured from stainless steel as standard,
  • Top plate drilled to fit iso 5211 dimensions. All handles, gear operators and pneumatic actuators are designed to mount directly.
  • STEM BUSHING : An upper stem bushing, retained by a stainless steel ring, is provided to absorb actuator side thrusts and is PTFE as standard.
  • STEM SEAL: Double "U" cup seal design is self-adjusting and gives positive sealing in both directions. Keeps environmental contaminants from entering the stem bore.
  • BODY: One piece wafer or lug style allows for ease of assembly and maintenance.
  • SEAT: Pascal's Replaceable tongue and groove seat design provides complete isolation of flowin media from the body. The seat also features a moulded o-ring which eliminates the need of flan gaskets.
  • DISC/STEM: One piece design. The disc edge is spherically machined and hand polished to produce a bubble tight shut off, minimum torque, and longer seat life. For erosion and abrasion resistance.
