TOGNELLA阀介绍

Single-acting flow control valves available from size 1/8" to 2" BSPP size, max. working pressure 400 Bar / 320 Bar, adjustable oil flow rate from 0,5 to 200 Lt/min. (depending on the size)

Technical description

The valves FT 257/5 have the function of regulating and, if necessary, to shut-off the flow in one direction, allowing a free flow in the opposite direction. Appreciated for their aesthetic characteristics that indulge positively the contructive directions of the equipments on which they are installed , they are also a reliable solution. The proper dimensioning has made possible to obtain, in a little space, a great mechanic resistance of the components. The spring in high-resistance material is housed in such a way that it does not close as a pack during the opening of the taper single-acting shutter valve.

Like all the valves of the series FT 257 they ensure:

• efficient metallic sealing;

• flow linearity at the opening;

• accurate control for a wide range of flow rate, thanks to the double reference system

• wide range of the flow rate control;

• impossibility for the needle to leave its seat even in the max. opening position;

• stable positioning thanks to a screw inside the knob;

• quick panel mounting (the ring nuts (G) are supplied on request). The check valve is set to 0,5 bar.

提供 1/8" 至 2" BSPP 尺寸的单作用流量控制阀，最大工作压力 400 巴 / 320 巴，可调节的油流量从 0.5 到 200 升/分钟。（视尺寸而定）

技术说明

阀 FT 257/5 具有调节功能，如有必要，可关闭一个方向的流动，允许相反方向的自由流动。由于它们的美学特征积极地满足安装它们的设备的构造方向而受到赞赏，它们也是一种可靠的解决方案。适当的尺寸设计使得在很小的空间内获得部件的巨大机械阻力成为可能。高阻材料弹簧的安装方式使其在锥形单作用截止阀打开期间不会成组关闭。

与 FT 257 系列的所有阀门一样，它们确保：

• 高效的金属密封；

• 开口处的流动线性；

• 由于双参考系统，可精确控制各种流速

• 流量控制范围广；

• 即使在最大位置，针也不可能离开其座位。开仓位置；

• 旋钮内有螺丝，定位稳定；

• 快速面板安装（环形螺母 (G) 可应要求提供）。止回阀设置为 0.5 bar。
