Parker Metric Ball Valves Series BVGL (Bar)Pressure Principle Operating pressures and temperatures Parker BVGL series valves are designed for use in fluid and gas applications and are DVGW approved. The valve dimensions are in 1/4" - 3/8" 30 1/2" accordance with DIN3357 for interchange- 3/4" ability and are available with BSPP female/ 1" female* long threads to DIN 2999 / ISO228. 11/4" These full flow ball valves have a chrome 20 11/2" plated ball with a double PTFE seal system 2" enabling the valve to be used with flow in either direction. All seals are treated with a silicone free lubricant enabling the valves to 10 be used in water based paint spray applica- tions.
