Please confirm your desired dimensions before placing an order. Thank you. This valve is made of industrial-grade brass, which is corrosion-resistant and easier to weld. It is ideal for high-temperature applications and can be used with gasoline, diesel, kerosene, natural gas, air, and other fuels. Due to the chemical composition of brass, this valve should not be used on projects involving potable water or other water conservancy projects. This valve is manufactured with a fluoroelastomer (VITON) seal. Fluoroelastomer is the most durable and high-performance rubber material, resistant to high temperatures, corrosive chemicals, and other fluids such as gasoline, diesel, motor oil, and lubricants. This high-response valve opens and closes within 1 second after actuation; this means it can instantly turn water on and off when power is applied or removed. Furthermore, our US-based SOLID engineers have determined that under proper operating conditions and maintenance, this valve has a service life of over one million cycles. Please note: This valve is not designed for continuous operation and should not be operated for more than 8 hours at a time; otherwise, the valve life will be shortened and the valve core may burn out.
