TOGNELLA阀FT290-14产品介绍
FT290隔离器针阀(直列式)通常用于保护压力表,因为它们具有双重功能:在打开时抑制压力波动,并完全隔离压力表。
采用高电阻钢压制而成,经过精确的处理,经过严格的测试,确保了可靠性和长寿命。
旋转的旋转螺母允许压力计精确定位。
标准提供并插入螺母中的密封件可防止接头和压力计之间的任何拉伸。
对于带锥形螺纹的压力表,必须使用本目录第182页所示的铜垫圈FT 1201(需另行要求)。适用于高达400巴的压力和-20°至+100°的温度,可根据要求使用对数螺母(G)进行面板安装。
The FT290 isolator needle valves (in line) are normally used to protect the pressure gauge since they have the double function of dampening pressure surge during opening and of isolating the pressure gauge entirely.
Pressed in high-resistance steel, protected by an accurate treatment,subjected to strict tests, they ensure reliability and long life.
A rotating swivel nut allows for accurate pressure gauge orientation.
The sealing, standard supplied, and inserted in the nut, prevents any drawing between the connection and the gauge.
For pressure gauge with taper threads, it will be necessary to use coppe washers FT 1201 shown on page 182 of this catalogue (to be requested separately). Suitable for pressure up to 400 bar and temperature from -20° to +100° they can be panel mounted by use of log nut (G),supplied on request.
