쓰리 웨이 컨트롤 밸브

쓰리 웨이 컨트롤 밸브는 단일 모듈레이팅 바디 내에서 두 유동을 합류 또는 분기합니다 — 두 스트림을 제어된 출구로 합치는 컨버징, 한 스트림을 나누는 다이버징 — 액추에이터 공간, 비용, 설치 대칭성이 중요한 곳에서 배관 티 + 투웨이 밸브를 대체합니다. 범위는 DN20~DN400, PN 16~PN 100 / Class 150~Class 600으로, 플랜지, RF, MF, RTJ 단자 접속, WCB/WC6/CF8/CF8M 바디, SS304/SS316/코발트-크롬 경면 합금 시팅, 선형·등퍼센트·퀵 오픈 유량 특성, Cv 1.6~690, 메탈 씰 누출 등급 IV 및 소프트 씰 등급 VI, 두 압력 시리즈(PN1.6-4.0 및 PN6.4)의 치수화된 DN15~DN300 범위에서 118 mm~698 mm 페이스 투 페이스 길이입니다. 선정은 컨버징 대 다이버징 임무, 포트 간 압력 평형, 투웨이 계열과 동일한 트림/누출 선택에 따라 결정됩니다.

Rangeability	50:1 rangeability with linear characteristic
Valve body material	WCB, WC6, CF8, CF8M
End connection types	Flanged, RF, MF, RTJ
Measured face-to-face length	118 mm to 698 mm across DN15-DN300 (PN1.6-4.0 series)
seat plug materials	SS304, SS316, cobalt-chromium hardfacing alloy
Pressure (source-defined)	PN 16 to PN 100, Class 150 to Class 600
allowable leakage	Metal seal: grade IV (0.01% rated capacity); soft seal: grade VI (foam grade)
Actuation Options	pneumatic diaphragm, piston, or electric actuators
control accessories	pneumatic positioner, electro-pneumatic positioner, limit switch, solenoid valve, air lock relay, volume booster, filter regulator (AFR), position transmitter
mixing vs diverting selection	mixing-type valves can also serve diverting duty at small differentials; for sizes above 4 in with considerable pressure differential the mixing type is more suitable
flow functions	mixing (two inlets, one outlet), diverting (one inlet, two outlets), bypass
port configurations	mixing configuration has two inlets and one outlet combining two streams; diverting configuration has one inlet and two outlets splitting one stream
pn rating by size	DN 65-125: PN 25; DN 150-300: PN 16; DN 350-450: PN 10, each max 100 °C (optional 250 °C)
Flange standards	DIN 2632 (PN 10), DIN 2633 (PN 16), EN 1092-2, ANSI Class 150, JIS B 2210 5K
stainless steel ratings	stainless steel bodies: PN25 for DN 65-125 mm, PN16 for DN 150-300 mm, PN10 for DN 350-450 mm
temperature control use	commonly applied where fluid temperature is adjusted through heat exchangers, e.g. heating and cooling circuits, marine diesel, calender presses
din size pressure temperature envelope	DN 15 to 500, PN 16 to 160, -196 to +550 °C
ansi size class alternative	an ANSI-version family of three-way control valves covers nominal sizes up to NPS 20 with pressure classes from Class 150 to Class 900 (documented in a separate ANSI data sheet)
operating temperature packing window	body without insulating section: -10 to +220 °C standard packing, up to +350 °C with high-temperature packing; metal bellows or metal seal versions extend to -196 to +550 °C
seat plug leakage class din	metal seat-plug seal leakage class 0.05 % of KVS per DIN EN 60534-4
mixing diverting conversion	conversion between mixing and diverting service by reversing the seat-guided valve plug
