Introduction to the MKH-SAE210-50-4414 High-Pressure Ball Valve

The part number MKH-SAE210-50-4414 designates a commercial-grade, high-pressure 2-way block ball valve engineered primarily for severe-duty industrial and hydraulic systems. Designed to handle demanding operational environments, this specific model alphanumeric code acts as a comprehensive blueprint. Each distinct segment of the part number serves as an indication of its mechanical footprint, pressure rating, physical size, and chemical compatibility.

Understanding how this series is indexed allows engineers and procurement specialists to quickly decipher the valve’s exact structural characteristics:

[ MKH ] — [ SAE210 ] — [ 50 ] — [ 4414 ]

   |          |          |         |
 Valve     Pressure     Size    Material
 Type       Rating     (DN50)     Code

• Valve Series Type (MKH): Indicates the core design framework, identifying it as a 2-way high-pressure block-style ball valve built for bi-directional flow control.

• Pressure Class (SAE210): Defines the connection style and maximum workload. It conforms to SAE J518 (Code 61) standards, rated for a working pressure of 210 bar (3,000 PSI).

• Nominal Diameter (50): Specifies the internal bore sizing of DN50, which translates to a standard 2-inch fluid pathway.

• Material Matrix (4414): The final four digits dictate the metallurgy and internal sealing elements. The 44 prefix denotes a robust Stainless Steel body and internal trim (typically 1.4571 / 316Ti), paired with a 1 for heavy-duty POM (Polyacetal) friction-reducing ball seats, and a final 4 for premium FKM (Viton) sealing O-rings.

By adjusting any individual segment of this standard indication, the series transforms to accommodate different industrial media, bolt thread pitches (Metric vs. UNC), or lower-cost carbon steel alternatives while maintaining the same physical geometry.

The alternative material part numbers for this specific DN50 (2") SAE 3000 (210 bar) configuration are organized below by body material:

Stainless Steel Body Series

These versions retain the high corrosion resistance of a stainless steel block body (typically 1.4571 / 316Ti) but change internal seals or seats: 

• MKH-SAE210-50-4414: Your original configuration. Built with Stainless Steel body/trim, POM seats, and FKM (Viton) seals. Perfect for universal chemical, fluid, and high-temp oil lines. 

• MKH-SAE210-50-4413: Swaps the internal O-rings to NBR (Nitrile). Best for water-glycol, air, and standard hydraulic mineral oils where Viton isn't required. [1]

• MKH-SAE210-50-4428: Built with Stainless Steel body/trim, POM seats, and FKM (Viton) seals. [1]

• MKH-SAE210-50-442A: Uses Stainless Steel body/trim, POM seats, and NBR (Nitrile) seals. [1]

• MKH-SAE210-50-4464 (PEEK / ATEX): Features high-temperature PEEK ball seats paired with FKM seals. Engineered for severe extreme-temperature environments or chemical processing. [1]

Carbon Steel Body Series

If the environment does not require stainless steel, shifting to a high-tensile Carbon Steel block drastically lowers unit costs for standard hydraulic systems: [1]

• MKH-SAE210-50-1128: Constructed with a Carbon Steel body, POM seats, and FKM (Viton) seals. A standard default line item for premium high-pressure hydraulic circuits.

• MKH-SAE210-50-112A: Constructed with a Carbon Steel body, POM seats, and NBR (Nitrile) seals. The most common cost-effective choice for industrial mineral-oil hydraulic systems. [1, 2]
