Shut-off and control valves


LE-LF type shut-off and control globe valve

This valve is designed according to API 602 Standard with forged body up to 50mm nominal size, for wide pressure-, and temperature ranges. The LE type valve is suitable for closing gas and liquid mediums streams while the LF type is suitable also for chocking. The valve seat and the disc is welded with Stellite 6 for the purpose of excellent abrasion 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 a stainless steel gasket ring. The valves can be manufactured with threaded valve seats on demand.
