- Pressure-Temperature Rating (Brass body)
Temperature (°C) | Max. Working Pressure (bar) | Remarques |
-10 ~ 50 | 16 (PN16 rating) | Ambient |
100 | 10 | |
120 | 7 | |
150 | 4 | |
Note: Brass globe valves are generally suitable for temperatures ≤150°C. Above 120°C, pressure must be derated. PTFE packing maximum service temperature is approx. 150°C.

Seat Test Pressure (water) | 17.6 bar |
Air Seat Test Pressure | 6 bar |
Allowable Differential Pressure | Full rated pressure (globe valves suitable for throttling) |
Leakage Rate | Metal seated: minimal leakage (API 598 allowable) PTFE seated: zero leakage |
Temperature Range (standard) | -10°C ~ +120°C (PTFE packing) |
Suitable Media | Water, oil, gas, non-corrosive and mildly corrosive media |
Flow Characteristic | Linear (for throttling) |
Connection Type | BSPT female taper thread (also available with BSPP if required) |
Stem Type | Rising stem (outside screw and yoke – OS&Y) |
- Caractéristiques principales
- 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)
- Tige montante – 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
- Installation & Operation Instructions
- 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.
- 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).
- Opération – Turn handwheel clockwise to close, counter‑clockwise to open. Globe valves may be used for throttling (partially open) without significant damage.
- Maintenance – If stem leakage occurs, tighten the packing gland nut. For disc or seat leakage, disassemble and replace the disc or grind the seat.
