The R2231015B (commonly referred to alongside its base part number 2231015-14B or 2231015B) is a high-performance, industrial-grade pilot-operated diaphragm solenoid valve. It is primarily engineered for the automatic control of fluid and gas flow in automation, air compressor systems, water filtration, and printing machinery (such as Grafmac equipment).

Key Specifications & Features

1. Valve Type: 2-Position, 2-Way (2/2-Way) Diaphragm Solenoid Valve.
2. Operation Mode: Pilot-operated. It typically functions as Normally Closed (NC), meaning it blocks fluid flow when unpowered and opens when electrical current is applied.
3. Size Configurations: Features a 1-inch or 1/2-inch (G1/2) threaded interface with an internal orifice nominal diameter of DN14 / DN15.
4. Body Material: Robust brass or stainless steel construction.
5. Sealing Options: Usually outfitted with high-durability elastomer seals like NBR (Nitrile), EPDM, or FPM (Viton) depending on the chemical compatibility needed for the fluid.
6. Pressure & Temperature Limits: Designed to handle maximum pressures up to 10 Bar (approx. 145 PSI). Coil insulation is rated to withstand sustained temperatures up to 180°C for continuous duty (100% ED rating).
7. Electrical Options: Depending on the specific variant purchased, it can be equipped with coils for 220V AC, 110V AC, or 24V DC power supplies.
8. Protection Class: IP65 rated against dust and water ingress.
