SPX Homogenising Valve Parts Spare Parts

Homogenising Valve Parts SPX

Homogenising valve parts SPX are critical components in high-pressure homogenisers. These parts directly determine pressure build-up, shear intensity, particle size reduction and long-term reliability of the homogenising system.

BOS Homogeniserssupplies OEM-compatible homogenising valve parts for SPX homogenisers, including plug valve systems, pilot valve configurations and microgap valve solutions.

If you are searching for specific SPX homogenising valve part article numbers or want to verify which parts match your homogeniser, you can consult our complete spare parts overview at homo valve parts or homo valve components.

SPX Homogenising Valve Parts for SPX Flow Homogenizers

SPX homogenising valve parts are critical components in the liquid end of SPX Flow homogenizers. The homogenising valve assembly is responsible for pressure drop, turbulence creation, and particle size reduction during the homogenisation process.

Bos Homogenisers supplies high-quality aftermarket SPX homogenising valve parts compatible with SPX Gaulin, SPX Rannie, and SPX industrial series machines. We also support systems operating with SS plungers, chrome coated plunger, inchromated plungers, ceramic plungers, and TC plungers, ensuring complete liquid end compatibility.

SPX Machines for Which We Deliver Homogenising Valve Parts

BOS Homogenisers supplies homogenising valve parts and spare parts for the following SPX homogeniser series:

What Are SPX Homogenising Valve Parts?

The homogenising valve assembly creates the pressure drop that enables particle size reduction. It converts hydraulic energy into mechanical shear forces through impact, cavitation, and turbulence.

A complete SPX homogenising valve assembly typically consists of:

• Valve seat
• Valve impact head
• Valve guide
• Springs and retainers
• Hydraulic or manual actuation components

Correct interaction between the valve system and the plunger system—whether using MC model plunger, Rannie model plunger, or BOS type plunger configurations—is essential for stable pressure control and optimal homogenisation performance.

Materials for SPX Homogenising Valve Parts

Valve components are exposed to extreme pressure, impact forces, and product abrasion. For this reason, material selection is critical.

• Tungsten carbide (TC) – Maximum wear resistance for abrasive products
• Stellite – High hardness and corrosion resistance
• Hardened stainless steel – Suitable for standard food applications
• Ceramic components – Excellent chemical resistance and durability

When operating with TC plungers or ceramic plungers, matching valve seat materials is important to prevent uneven wear.

SPX Single-Stage and Two-Stage Valve Systems

SPX homogenizers are available with:

• Single-stage homogenising valves
• Two-stage homogenising valves (primary + secondary stage)
• Hydraulic actuation systems (HVA)
• Automatic hydraulic systems (AHS)

Proper valve adjustment ensures consistent pressure generation from the plunger system, whether operating with SS plungers, inchromated plungers, or chrome coated plunger configurations.

Wear Mechanisms in SPX Homogenising Valve Parts

Common wear mechanisms include:

• Impact erosion at the valve seat
• Abrasive wear from product particles
• Cavitation damage
• Corrosion from cleaning chemicals

Operating with worn valve parts increases load on the plunger system and may shorten the life of MC model plunger, Rannie model plunger, and BOS type plunger components.

When to Replace SPX Homogenising Valve Parts

Replacement is recommended when you observe:

• Pressure instability
• Reduced homogenisation efficiency
• Increased vibration or noise
• Visible wear on seat or impact head

Timely replacement prevents secondary damage to cylinder blocks, packings, and plunger assemblies.
