Diaphragm Valves
Harvel LXT® diaphragm valves are engineered to provide accurate throttling control and shut-off, utilizing a positive-stop, non-rising stem. The Weir-type design incorporates a PTFE diaphragm for maintaining purity, and uses EPDM o-ring seals on the union connections. Low-profile True Union design minimizes space while allowing for ease of installation and maintenance. Valves are supplied with both socket and threaded-end connectors for versatility. They incorporate a built-in position indicator, and are operated with a high-impact, hand-wheel-style handle for easy operation.
Harvel LXT® diaphragm valves are available in sizes 1/2" through 2" and carry a maximum pressure rating of 150 psi, non-shock @ 73°F. |

NOTE: Harvel LXT® True Union diaphragm valves sizes 1/2" - 2" carry a maximum pressure rating of 150 psi for water, non-shock, @73°F.
Ball Valves
Harvel LXT® quarter-turn true union ball valves incorporate the same high degree of unique engineering design characteristics. Among these characteristics are heavy-bodied construction with strong buttress threads, full Schedule 80 bore to minimize pressure drop, PTFE floating seat design to minimize seat wear, EPDM or Viton® o-ring seals, Safe-T-Shear® stem, socket and threaded-end connectors, and True Union design for ease of installation and maintenance.
Harvel LXT® ball valves are available in sizes 1/2" through 4". 1/2" through 2" T.U. ball valves carry a maximum pressure rating of 235 psi, non-shock @ 73°F. 3" and 4" carry a maximum pressure rating of 150 psi, non-shock at 73°F.
