High reliability due to thick-walled PFA lining: universal resistance and maximum permeation resistance. Safety also at high pressures and temperatures due to heavy-duty bellows. Easy to maintain: seat and plug individually replaceable. PTFE bellows with stainless steel support rings or Hastelloy C-bellows. HV version with on-off plug, HVR version with control plug.
