Brand: LESER |

The LESER high pressure safety valves are full lift spring loaded safety valves which are used at high operating pressures (>= 40 bar/>= 580 psig), often in conjunction wiht high operating temperatures (>= 400ºC/>= 752ºF). The high pressure safety valves are designed to withstand these extreme service conditions through their robust construction, selection of materials, fit matching for the sliding parts, and the use of high temperature fittings. |
