Pneumatic Valve Body, HP, 2-Port, 60K PSI | HJ-10189181
The HJ WATERJET HP Pneumatic Valve Body, 2-Port, 60K (HJ-10189181) is a precision-machined 60K PSI waterjet valve housing engineered for KMT-style high-pressure pneumatic valve assemblies and cutting heads. Designed to deliver structural integrity, reliable sealing surfaces, and long-term durability, the HP Pneumatic Valve Body, 2-Port serves as the core foundation of the valve assembly, supporting internal components and ensuring consistent, leak-free high pressure water flow in demanding environments up to 60,000 PSI.
Manufactured from high-strength stainless steel, it provides superior resistance to corrosion, moisture, and chemical exposure, making it ideal for food-grade, washdown, and harsh industrial applications.
The HJ-10189181 HP Pneumatic Valve Body, 2-Port, 60K is used in square-body pneumatic valve systems and cutting head assemblies.

Frequently Asked Questions
1. What is HJ Waterjet part number HJ-10189181?
HJ Waterjet HJ-10189181 is a direct replacement for KMT 10189181 which identifies as a 2-port high-pressure pneumatic valve body designed for 60,000 PSI (4,100 bar) waterjet systems. It provides the main housing for the internal pneumatic valve components.
2. What is HJ-10189181 used for?
It is used in 60K PSI KMT pneumatic valve assemblies, including waterjet cutting systems that use a square-body 2-port pneumatic valve configuration.
3. Is HJ-10189181 a complete valve?
No. HJ-10189181 is the valve body, not the complete pneumatic valve assembly. Internal components such as the valve stem, seat, seals, backup rings, and actuator are separate components.
4. Is HJ-10189181 used on 90K PSI waterjet systems?
No. HJ-10189181 is listed for 60K/4,100-bar applications. A different body, HJ-20475871, is listed for 90K/6,200-bar UHP pneumatic valves.
5. Can I replace only the HJ-10189181 valve body instead of the complete valve?
Yes, when the internal valve components are still serviceable. Replacing only the body can be appropriate when the existing body is damaged, worn, corroded, or otherwise no longer suitable for service.
6 What are the common symptoms of a bad HJ-10189181 valve body?
Potential symptoms include water leakage, inability to maintain proper valve operation, damaged sealing surfaces, corrosion, visible cracking or deformation, and inconsistent valve performance. However, leakage or poor valve operation can also originate from the internal seals, seat, stem, or actuator.
7. Is HJ-10189181 made of stainless steel?
The HJ-10189181 pneumatic valve body is a stainless-steel 2-port body for 4,100-bar applications.
8. What is the difference between HJ-10189181 and HJ-20427648?
Both are 60K PSI pneumatic valve bodies, but they serve different configurations. HJ-10189181 is the 2-port body, while HJ-20427648 is a 3-port stainless-steel body used for KMT 3-port HP pneumatic dump valves.
9. What is the difference between HJ-10189181 and HJ-20475871?
The key difference is pressure/application: HJ-10189181 is for 60K PSI/4,100-bar 2-port HP valves, while HJ-20475871 is for 90K PSI/6,200-bar UHP pneumatic valves.
