RETZ瑞茨『进口气动截止阀』详细介绍●RETZ截止阀系列●RETZ气动截止阀●产品数据
?进口气动截止阀描述--
RETZ气动截止阀采用顶导向结构，配用多弹簧执行机构，开启轻松灵活，当执行器给压时，阀瓣开启。当执行器卸压时阀门自动关闭，本阀采用止回阀原理，只能单向截断。
RETZ pneumatic cut-off valve adopts a top guide structure, with multiple spring actuators. It opens easily and flexibly. When the actuator is pressurized, the disc opens. When the actuator is released, the valve automatically closes. The valve adopts the check valve principle and can only be truncated one way.
?进口气动截止阀特征--
◇结构紧凑、重量轻、动作灵敏、压损失小、拆装方便
◇设计成截面低流阻流道，容量大,额定流量增大
◇阀内件密封部分有堆焊硬质合金和软密封两种，关闭进密封性能优良。
◇平衡型阀内件，提高了切断阀的许用压差。
◇波纹管密封型对移动的阀杆形成完全的密封，堵绝了介质外漏的可能性。
◇泄漏量等级为IV级或VI级,流量特性为快开
◇保证阀杆的零泄漏，提供无需维修条件
1. compact structure, light weight, sensitive action, small pressure loss, convenient disassembly and assembly.
2. it is designed as a low flow resistance channel with large capacity and increased rated flow.
The sealing parts of the 3. valve internals include two kinds of hardfacing alloy and soft seal.
4. the balancing valve internals improve the allowable pressure difference of the shut-off valve.
5. bellows seal type to the mobile stem to form a complete seal, blocking the possibility of medium leakage.
6. the leakage level is IV or VI, and the flow characteristics are fast.
7. ensure zero leakage of valve stem and provide no maintenance condition.
