  1. Klíčové vlastnosti
  • Globe valve design – Suitable for both shut-off and throttling service; good flow regulation characteristics
  • Brass body – Good corrosion resistance, machinability, and economy
  • BSPT taper threads – Reliable leak-tight seal without additional sealants (PTFE tape recommended for installation)
  • Stoupající stonek – Visual indication of valve position (stem rises when opening)
  • Replaceable packing – Easy maintenance
  • Integral seat – Leak-proof body-to-seat construction
  • Bi-directional sealing (recommended installation with pressure under the disc)
  • Wide size range – From 1/4″ to 4″ for various system requirements
  1. Installation & Operation Instructions
  1. Thread connection – Apply PTFE tape or thread sealant to the male BSPT thread. Screw the valve onto the pipe. Do not over‑tighten to avoid body cracking.
  2. Flow direction – Globe valves are directional. The arrow cast on the body indicates the recommended flow direction (pressure should be under the disc for better shut-off and packing life).
  3. Operace – Turn handwheel clockwise to close, counter‑clockwise to open. Globe valves may be used for throttling (partially open) without significant damage.
  4. Maintenance – If stem leakage occurs, tighten the packing gland nut. For disc or seat leakage, disassemble and replace the disc or grind the seat.
