Manfaat

  • Added safety due to pressure seal design providing increased sealing to atmosphere: The higher the pressure in the valve body, the tighter the cover joint. Very low risk of leakage, particularly at high pressures and temperatures. Compact design.
  • Reliable, tight shut-off and service-friendly design due to flexibly mounted valve disc. Precise alignment of valve disc with body seat; valve disc is easy to replace.
  • Hard-faced seat/disc interface made of wear-resistant and corrosion-proof 17 % chrome steel or Stellite for long service life and high functional reliability.
