Knife Gate Valves

Specifically designed for thick slurries and media with suspended solids.

Features include: A sharp, beveled blade to cut through dense materials.

Resilient or metal-seated designs for tight shut-off.

Minimal cavity to prevent material accumulation.

 

Pinch Valves

Ideal for abrasive slurries with high solid content. Advantages include:

Full-bore design providing unrestricted flow.

Isolating the process media within a replaceable sleeve.

Minimal contact between moving parts and slurry.

 

Diaphragm Valves

Suitable for corrosive and abrasive slurries. Benefits feature:

A flexible diaphragm isolating the valve body from the flow path.

No internal pockets where solids can collect.

Excellent for throttling control.

 

High-Consistency (HC) Ball Valves

Engineered for pulp stocks with up to 20% fiber consistency. Key attributes:

Specialized trim and enlarged ports to prevent fiber plugging.

Robust sealing materials resistant to wear and chemical attack.

Smooth surface finish to minimize fiber adhesion.

 

Clamp Valves (Dump Valves)

Widely used in pulp processing and stock preparation. Characteristics include:

Fast-acting operation for batch processes.

Full, unobstructed flow path in the open position.

Durable construction for handling high-consistency pulp.

 

Specialty Control Valves

For precise regulation of chemical dosing, steam, and stock flow. Features include:

Anti-cavitation and noise-reduction trim.

Corrosion-resistant alloys (e.g., duplex stainless steel).

Advanced positioners for accurate control.

Valves for Slurry Applications

At SHIELD Eng. and Tech. Co. Ltd., our valves are built to excel in these harsh environments through:

 

Robust Design: Finite Element Analysis (FEA) optimized structures for pressure integrity and long life.

 

Precision Manufacturing: Advanced CNC machining ensures perfect sealing surfaces and dimensional accuracy.

 

Customization: We tailor valve specifications—materials, actuation, lining, and port sizes—to your exact process conditions.

 

Rigorous Testing: Every valve undergoes pressure, leakage, and operational testing before shipment.
