The Mark 518 is a back-pressure regulator for use in low pressure air and gas services. With a selection of six pressure ranges, set points can be chosen to control back-pressures from 1" w.c. to 7 psi (3mbar to 0,5 bar). As a standard feature, the MK518 is provided with soft seals for ANSI Class VI shutoff. The valve is also leak-proof under vacuum conditions. The Mark 518 back-pressure relief valve is used for maintaining the pressure of air and gases in the positive inches w.c. (mbar) pressure range.
  • Completely self-operated – Spring-loaded regulator operates off of process pressure and requires no external power source or air supply for operation

  • Wide range of low back-pressure settings – Choose from six pressure ranges for set points ranging from 1” w.c. to 7 psi (3mbar to 0,5 bar)

  • Long service life – All metal wetted parts produced from stainless steel or Hastelloy C for durability and long life

  • Tight shutoff – Soft seats for ANSI Class VI shutoff

  • The Mark 518 back pressure relief valve is used for maintaining the pressure of air and gases in the posi-tive inches w.c. pressure range
