Product Name: Abrasive Flow Control Block

Description:
This component is a flow control block, also known as a sand valve block or abrasive metering block, designed for the abrasive delivery system of waterjet cutting equipment. It is a precision-machined component that serves as the core flow-regulating element within the abrasive regulator (sand valve) assembly. The control block works in conjunction with a throttle screw to precisely meter the volume of garnet abrasive entering the cutting head mixing chamber.

Applications:

• Regulates abrasive flow rate in the sand valve assembly of abrasive waterjet cutting systems

• Controls garnet delivery into the mixing chamber for optimal cutting efficiency

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar)

Features:

• Precision-Machined Surfaces: Flow control surfaces are machined to exact tolerances for consistent abrasive metering

• Wear-Resistant Material: Constructed from hardened steel or stainless steel to resist erosion from abrasive particle flow

• Variable Flow Control: Provides continuous adjustment of abrasive flow rate when actuated by the throttle screw

• Corrosion-Resistant: Treated to withstand abrasive dust and moisture exposure

Maintenance:

• Interrupted Flow: If abrasive flow stops during operation, the control block area may be blocked by foreign objects (small stones, paper debris) or compacted abrasive dust

• Throttle Orifice Blockage: Abrasive particles can lodge in the flow passage, preventing proper regulation. Disassemble and clean thoroughly

• Sealing Surface Wear: Replace the control block if the sealing surface shows visible wear, erosion, or deformation

• Gap Adjustment: After installation, maintain a gap of approximately 0.05 mm between the throttle screw tip and the control block. Verify the valve core moves freely

• Cleaning: Regularly clean the control block with compressed air to remove abrasive dust and debris

• Full Depressurization: Always fully depressurize the waterjet system before servicing the abrasive valve
