Your cart is empty.Valve positioners for all manifolds currently on the market are subject to mechanical wear. Use the valve replacement kit to get your digital manifold from Testo working again really quickly. Replacing the valve positioners is very easy and can be carried out independently on site. With the valve replacement kit, you can replace two valve positioners - on the high pressure and low pressure side, or at the two middle connections on the digital manifold. Please order another kit if you would like to replace all 4 valve positioners.

Nice, but why do I need the parts that almost never wear out?

My original knobs stopped working so it was open all the time on the low side. These were easy to install and have been working perfectly

I've purchased this product because my manifold gauge was leaking, after I've repaired it , it works like its brand new again, the Testo digital gauges are not cheap, so if you can fix it for under $90 it's worth saving it....

Installed the new valve bodies as per instructions. I’ve done two service calls today and my gauges now maintain a solid reading. After Shipping it was total of $40 to revive my once $400 gauges (5 years ago)

Right part and right price. The Testo 570 gauges are the best I have ever used. After 10 years of use, the knob broke. Glad that parts are so available.
