LCT type wedge gate valve

This forged body gate valve is manufactured according to API 602 Standard, with up to 50 mm nominal size, for wide pressure-, and temperature range. The design is of rising stem with non-rising handwheel. The seat rings pressed into the body and the gate is welded with Stellite 6 for the purposes of excellent wearing resistance. The packing of the stuffing box is graphite (or Teflon) rings, which can be replaced during operation as well in the uppermost position of the stem. The sealing of the bonnet is highly flexible spiral wound gasket. For higher pressures the sealing is made of stainless steel ring.
