  1. Hauptmerkmale
  • Brass body – Good corrosion resistance and machinability; suitable for water and low pressure steam
  • BSPT taper thread – Reliable sealing, easy installation; no need for additional sealing tape
  • Non-rising stem design – Compact construction, ideal for space‑limited installations
  • Full bore or reduced bore – Typically reduced bore (slightly lower flow capacity than pipe size)
  • Low operating torque – Light handwheel operation
  • Cost effective – Widely used in construction, HVAC, water supply and drainage
  1. Installation & Operation Instructions
  1. Thread connection – Apply PTFE tape or thread sealant to BSPT male threads. Screw in clockwise. Do not over‑tighten to avoid cracking the valve body.
  2. Flow direction – Gate valves generally have no flow direction restriction, but it is recommended to install with the arrow (if marked) or horizontally.
  3. Betrieb – Turn handwheel clockwise to close, counter‑clockwise to open. Valve should be fully open or fully closed; not suitable for throttling (may erode sealing surfaces).
  4. Maintenance – If stem leakage occurs, carefully tighten the packing gland nut. If leakage persists, replace the packing.
