Orifice flow restrictor VHCA series

This high pressure jet flow restrictor is a compact, multi-orifice flow restrictor that incorporates slots and spin chambers. The complex fluid passage provides a greater minimum passage for a given restriction and is better suited to handle much higher levels of contamination. Additionally, the fluid velocity is reduced by the series of restrictions, thus reducing the chances of cavitation. With robust screens protecting for bidirectional flow, the High Pressure 187 Multi-Orifice Visco Jet® Restrictor is available calibrated to ± 5% or ± 10% tolerance. - Type: Multi-Orifice - Diameter: 0.187 inches - Metered Flow Range: 11,200 to 313,000 Lohms - Test Fluid: Water - Operating Pressures: Up to 8000 psi General Performance - Lohm Rate Tolerance: ± 5% or ± 10% - Maximum Working Pressure: 8000 psid - Nominal Weight: 2.0 grams Materials - Body: 304L CRES (QQ-S-763) - Pin: 17-4PH CRES (AMS 5643) - Spacers: 303 CRES (QQ-S-763C) - Visco Stack: 304L CRES (ASTM A 666) - Retainer: 17-4PH CRES (AMS 5643) - Screens: 304L CRES (ASTM A 666) - Base Washer: 304L CRES (ASTM A 666) - Braze: - (AMS 4774) - Finish: All CRES Parts Passivated.
