Specifications
.Size: 50-300mm
Features
  • Resilient orifices: seal from very low to high working pressure (0.1-25.0 bar)
  • ABS float: proven long lasting material specific gravity (0.75-0.80)
  • No protruding levers: this feature reduce maintenance and servicing to a minimum
  • No premature closing
  • Standard: comply with JIS B2063
  • Small orifice: automatically releases accumulated are in pipelines
  • Large orifice: automatically releases or admits large volume of are for efficient filling or emptying of pipelines to protect against vacuum or pipeline damage
