公称通径DN15 – DN150
公称压力PN16 PN25 PN40 ANSI150 ANSI300
温度范围-10℃ - 200℃
The control equipment consists of a stainless steel ball valve and a pneumatic
quarter-turn actuator, a hand-lever or a gear-operated actuator.
The valves, which are of modular construction have the following features:
• Seatring live-loaded at one side or with floating ball.
• “Open-Close” - operation with particularly low leak rate”bubble-tight version”.
• Exchangeable bore seal in TFM.
• Stem sealing by means of a cup spring live-loaded V-ring packing.
• Blowout-proof stem.
• Face to face serie 1 acc. to EN 558 ( F1 acc. To DIN 3202 ).Face to face serie
27 acc. to EN 558 (F4 / F5 acc. To DIN 3202 ).
• Connecting flange for actuators acc. to DIN ISO 5211.
Versions:
Ball valve Series 26d alternatively in the following designs:
• Ball valve with hand-lever (DN 150 with gear operator).
• Ball valve with gear-operated actuator.
• Ball valve with pneumatic quarter-turn actuator.
