PIETRO FIORENTIN调压阀DIVAL系列介绍
DIVAL系列气压调节器是弹簧式气压调节器,具有平衡的阀塞,膜片指令和通过弹簧进行的对比作用,适用于低压,中压和高压。
潜水阀和切断装置的串联调节器配有内部感应线。调节器和切断装置都已预先设置,可以由客户连接到外部传感器管线,与下一页的流量图有关。它们广泛用于民用或工业工厂,使用天然气或液化石油气或非腐蚀性气体。
得益于平衡插头的概念,可以实现:
高流量系数;
即使在最大流量下也高度准确;
减小了锁定压力区和锁定压力;
减少响应时间;
在零流量下没有内部泄漏;
失败打开类型;
定期维护,无需从管道上拆下阀体;
即使在已经安装的调压器上也可以安装紧急关闭阀(OPSO / UPSO),而无需修改现有管道。
DIVAL series gas pressure regulators are spring-loaded gas regulators with balanced plug, diaphragm command and contrast action by spring, suitable for low, medium and high pressures.
Divals and shut-off device series regulators are supplied with internal sensing lines. Both regulator and shut-off device are preset for connection to an external sensor line by the customer, related to flowrate diagram on next page. They are widely used either in civil or industrial plants, using natural gas or LPG or non-corrosive gas.
Thanks to the concept of balanced plug to achieve a:
High flow rate coefficient;
Highly accurate , even at maximum flow rates;
Reduced lock up pressure zone and lock up pressure;
Reduced response times;
No internal leakage at zero flow rate;
fail open type;
Regular maintenance without disassembling the body from pipes;
possibility to incorporate the slam-shut (OPSO/UPSO) even on regulators already installed, without modifying the existing pipes.
