Pressure-Temperature Rating (Brass body)

Temperature (°C)	Max. Working Pressure (bar)	비고
-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.

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)

주요 특징

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)
라이징 스템 – 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).
작업 – 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.
