This valve performs well and is built to last. Made of 304 Stainless Steel with high-temperature tolerant Teflon® seals, the valve is durable and can be easily dismantled for cleaning. The full-bore ball port provides excellent flow-through with almost no pressure loss, and the Weldless Bulkhead includes all the seals and lock nuts needed to install the valve in any thin-walled container. Just drill a hole 13/16″ to 7/8″ wide, mount the valve, and tighten the nut. The Female adapter on the bulkhead allows for additional components with Male NPT fittings to be easily attached to the valve inside the container.
