valve body in two parts, valve plug and spring, assembled by means of a clamp ring and hygienically sealed with a special seal ring. A guide disc with four legs ensure alignment of the spring-loaded valve plug with an o-ring seal. The valve is available with weld and clamp ends for ISO and DIN tubing connections.Working principleThe Alfa Laval LKC UltraPure Non-return Valve opens and closes depending on the pressure. The spring acts on the valve plug and keeps the valve closed until the force from the pressure in the inlet exceeds the force of the spring. If a reverse flow should occur, the spring force and the pressure from the outlet will keep the valve closed.

Mounting orientationExternal Connection Precautions for connectionWe recommend peeling off 4 to 5mm of the tip of the lead wire and neatly soldering it before connecting.If it is not soldered, the lead wire may come loose when inserted into the terminal block, causing short-circuit with adjacent terminals. Therefore, careful handling is required.1. Power supply [24VDC]Use a constant voltage switching power supply with 1.3A or more of 24+/-2VDC current capacity.2. Command signal [SIGNAL]The signal is controlled by manual potentiometer or external command signal (0 to 5VDC). The signal is controlled by manual potentiometer or external command signal (0 to 5VDC).Since input impedance is 100kΩ, the current required for external command signal is not more than 0.05mA.In case of external command signal, use in an isolated condition (not common grounded) by separating the power for signal from that of power amplifier drive.3. Output [OUTPUT]Use the output cable (connecting to the electro-pneumatic proportional valve) with a conductor sectional area of 0.75mm or 1.25mm2 and keep the length so that the impedance of the output cable only (2Ω in total of plus and minus sides) does not exceed 1Ω.For example, if using JIS C 3306 1.25mm2, the 60m long output cable (120m long in total of plus and minus sides) is applicable.4.

这个步骤一般用户只做检查即可，已经出厂调整过。
如果确实差异很大就必须进行调整。
