Air pressure relief valve CCPI series

stainless steelcartridgedirect-operated

This cartridge safety pressure relief valve offers superior flow capacity for its size. It is designed specifically for installation into plastic housings or fittings and can be installed in either direction to provide forward or reverse flow capabilities. Featuring a high quality metal seat, this direct-acting relief valve delivers low leakage, repeatable cracking pressure, low hysteresis, and long life. The valve is 100% functionally tested to ensure performance. - Mounting Configuration: Press-In - Into Plastic - Diameter: 4.69 mm - Full Open Lohm Rate: 250 Lohms - Maximum Working Pressure: Dependent on Housing Material - Relief Pressure Range: 100 to 625 kPa General Performance - Full Open Lohm Rate: 250 Lohms - Leakage: 10 SCCM (max) at 172 kPa (25 psid) on Air - Maximum Working Pressure: Dependent on Housing Material, Configuration, and Operating Conditions Materials - Body: 303 Stainless Steel - Cage: 305 Stainless Steel - Spring: 302 Stainless Steel - Ball: 440C Stainless Steel Part Numbers & Specifications - Part Number: CCPI4510100S - Lohm Rate: 250 Lohms - Cracking Pressure: 100 +/- 15 kPa (14.5 +/- 2.2 psid) - Installation Hole Drawing Number: 1INST055825S - Approximate Weight: 0.5 grams Cracking pressure is defined as the pressure at which uprun flow exceeds 50 SCCM of air.
