ASZ type needle valve

This inside threaded needle valve is of simple design for wide pressure range. Long life is ensured by the non-rotating, self-centering valve tip and also by the weld on valve seat. The needle valve can be made with flanged, threaded, butt welded and socket welded ends as well. The needle valve can be built in the streamline of the pipeline in the direction of the arrow located on the valve body.

ASZ


KFSZ type needle valve

The KFSZ type needle valve stainless steel design made for up to 10000 psi (690 bar) nominal pressure. Long life is ensured by the non-rotating, self-centering tip and the male thread, which is out of contact with the medium located over the stuffing box and the plastic stem guard. Depending on the order the needle valve can be manufactured with connecting threads of NPT 1/2” outside or inside, and also M20x1,5 inside. The valve body can be blow off by the vent plug located on its bottom. The needle valve can be built in the streamline of the pipeline in the direction of the arrow located on the valve body.

Pressure range: 0 - 10000psi
Temperature range: - 60°C - +150°C

Main features:

  • Stainless steel design
  • Went plug for body pressure relief
  • NPT 1/2” or M20x1,5 connecting threads
  • Self-centering tip, closing on conical surface

Design options:

  • Connecting threads on customer demand

Material:

  • ASTM A479 316(L)

Design standards:

  • Threaded type: ASME B1.20.1 NPT; ISO 965
  • Pressure test: API 598; EN 12266-1
  • NACE design: NACE MR0175 / ISO 15156

KFSZ


LM-1 type manometer needle valve

The LM-1 type manometer needle valve makes possible the connection of the manometers to pipelines. The valve body is a four way cock, and can be manufactured with NPT 1/2” or M20x1,5 connecting threads depending to the order. The valve body can be blown off to provide easy installation or dismantling under pressure as well. The manometer needle valve can be built in the streamline of the pipeline in the direction of the arrow located on the valve body.

Dimension: DN 15
Pressure range: PN 40 – 350
Temperature range: - 60°C - +150°C

Main features:

  • Went plug for body pressure relief
  • NPT 1/2” or M20x1,5 connecting threads
  • Self-centering tip, closing on conical surface
  • Weld on valve seat

Design options:

  • Handlever design
  • Handwheel design
  • Connecting threads on customer demand

Materials:

  • ASTM A350 LF2
  • ASTM A479 316(L)

Design standards:

  • Threaded type: ASME B1.20.1 NPT; ISO 965
  • Pressure test: API 598; EN 12266-1
  • NACE design: NACE MR0175 / ISO 15156
