Pressure-Temperature Rating (ASME B16.34 – CF8 body, Material Group 2.1)

Temperature (°C)	Max. Working Pressure (bar)	비고
-29 ~ 38	16.0 (PN16 rating)	Ambient
100	12.0
150	9.8
200	8.1
250	6.6
300	5.2
350	4.2
400	3.2
425	2.5

Note: CF8 (304) has lower high-temperature strength than CF8M (316). The maximum continuous operating temperature for PTFE seats is approximately 150°C. For higher temperatures, PEEK or metal seats must be selected. The pressure ratings above are based on the body material; actual service temperature is limited by the seat material.

주요 특징

2-piece body – Easy inline maintenance; seats and seals can be replaced individually
Floating ball design – Ball is supported by seats on both ends; medium pressure pushes the ball against the downstream seat for tight shut-off
Full bore – No flow restriction; ideal for low pressure drop applications
Bi-directional sealing – PTFE seats provide zero leakage shut-off
CF8 stainless steel body – Good corrosion resistance for media compatible with 304 stainless steel
Anti-static device (optional) – Prevents electrostatic charge accumulation
Fire safe design (optional) – Compliant with API 607

작동 옵션

Actuation Type	비고
Lever + limit stop	Suitable for manual operation of DN100; moderate torque
Worm gear operator	For frequent operation or higher torque requirements
Electric actuator	On-off or modulating (4-20mA); direct mounting on ISO 5211 top flange
Pneumatic actuator	Double-acting or spring-return; with solenoid valve and limit switches
