Over 20,000 EHCOTECH 21-Series valves have been delivered to hobbyists, businesses and manufacturers. EHCOTECH B21V-1/2-CC-12VDC SOLENOID VALVE This is a great general purpose valve for many water, air, fuel, or gas projects. General 1/2" NPT Ports (0.840" outer thread diameter); NPT is the U.S. standard pipe thread 12-Volt DC 2-way, Normally Closed (energize to open, de-energize to close)FKM (Viton) diaphragm Semi-Direct Acting Valve (allows for good low pressure performance)Large internal orifice (5/8" or 16 mm internal orifice diameter)Cv value: 4.8Pressure and Temperature 0 to 145 psi or vacuumMax media temp: 265° F (130° C)Zero differential pressure valve Gravity feed capable (For best gravity feed performance we recommend EHCOTECH motorized valves) Suitable Media Water, Air, Various Gases Diesel Fuel, Gasoline, Glycol Other media compatible with FKM (Viton)NOTE: do not use general purpose valves for Natural Gas. Natural Gas valves are optimized for 0 to 0.5 psi range.Electrical 12-volt DC / 1.4 AmpsCoil tempreature will stabilize between 155° and 185° F during long activation periods (typical for general purpose solenoid valves) Contact us regarding applications requiring a very large number of cumulative activation hours Dimensions Height: 4"Width: 2"Length: 2-3/8"Weight: 1 lb 8 oz ## Features - 1/2" NPT inlet / outlet port threads | 1/2" or 15 mm internal orifice | 2-way | Unidirectional - 12V DC coil, 1.4 Amp current draw, 8" lead wires, no polarity requirement for wiring - Normally Closed (Energize to open, de-energize to close) - Brass Body, FKM (Viton) diaphragm, Stainless Steel internal parts - 0 to 145 psi, 265 F max media temp, Cv 4.8 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E0NS84C | | Brand Name | EHCOTECH | | Customer Reviews | 4.4 4.4 out of 5 stars (15) | | Exterior Finish | Stainless Steel | | Inlet Connection Size | 0.5 inches | | Inlet Connection Type | National Pipe Tapered | | Manufacturer | EHCOTECH | | Manufacturer Part Number | B21V-1/2-CC-12VDC | | Material Type | Viton,Brass | | Number of Items | 1 | | Number of Ports | 2 | | Unit Count | 1 Count | | Valve Type | solenoid valve | ## Product Details - **Brand:** EHCOTECH - **Exterior Finish:** Stainless Steel - **Inlet Connection Size:** 0.5 inches - **Inlet Connection Type:** National Pipe Tapered - **Manufacturer:** EHCOTECH - **Material:** Viton,Brass - **Number of Items:** 1 - **Number of Ports:** 2 - **Unit Count:** 1 Count ## Images ![1/2" NPT Brass Electric Solenoid Valve 12-Volt DC (12VDC) FKM/VITON Normally Closed, N/C, Water Air Gas Fuels - Image 1](https://m.media-amazon.com/images/I/51YEq+EBSTL.jpg) ![1/2" NPT Brass Electric Solenoid Valve 12-Volt DC (12VDC) FKM/VITON Normally Closed, N/C, Water Air Gas Fuels - Image 2](https://m.media-amazon.com/images/I/41FFN5FSIlL.jpg) ![1/2" NPT Brass Electric Solenoid Valve 12-Volt DC (12VDC) FKM/VITON Normally Closed, N/C, Water Air Gas Fuels - Image 3](https://m.media-amazon.com/images/I/41hvGcfXG+L.jpg) ![1/2" NPT Brass Electric Solenoid Valve 12-Volt DC (12VDC) FKM/VITON Normally Closed, N/C, Water Air Gas Fuels - Image 4](https://m.media-amazon.com/images/I/81t-5sjUGWL.jpg) ## Questions & Answers **Q: Will this piece work for auxiliary tank in the back of my truck to gravity feed to the main tank for diesel fuel** A: Yes it will work for gravity feed of liquids. **Q: What is the air cfm rate on this solenoid? need reply asap** A: Flow rates are dependent on pressure. At 100 psi, you can expect approximately 14 CFM with air. At 120 psi, you can expect approximately 18 CFM. **Q: Is this valve suitable for propane? Low pressure regulated side for a stove.** A: I don't think I would use it for that I think it said not to use it for gasses it's great for air and water **Q: Is there a flow rate specification? I need at least 3 GPM at a 5 PSI in/out difference with water.** A: The Cv value is 4.8. Based on the Cv value and your 5 psi pressure differential between inlet and outlet side, this valve will flow significantly more than 3 GPM. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/27657838-1-2-npt-brass-electric-solenoid-valve-12-volt-dc](https://www.desertcart.com.ar/products/27657838-1-2-npt-brass-electric-solenoid-valve-12-volt-dc) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-12*
