Iwata Neo Needle Packing Screw for Neo CN / BCN # 1251

The Needle Packing Screw is a component of the Neo series of needle valves that is designed to hold the needle packing in place.

It is typically made of high-strength steel and is threaded to allow for easy installation and removal.

The Needle Packing Screw is responsible for creating a tight seal around the needle of the valve, preventing leaks and ensuring smooth operation.

It works in conjunction with the needle packing material, which is compressed around the needle by the screw to create the seal.

To use the Needle Packing Screw, it is first threaded into the valve body and tightened to hold the needle packing securely in place.

The needle of the valve is then inserted through the packing and tightened with the screw to create the seal.

In summary, the Needle Packing Screw is a critical component of the Neo needle valve series that holds the needle packing in place, allowing the valve to create a tight seal and operate smoothly.
