The first half includes a first pipe member and the second half includes a second pipe member. A first end of the first pipe member is a fluid inlet port and a second end of the second pipe member is a fluid outlet port. The enclosed cavity defines a first pocket and a second pocket each in fluid communication with a first lumen of the first pipe member and a second lumen of the second pipe member. A first valve assembly is positioned in the first pocket and a second valve assembly is positioned in the second pocket. Each of the first valve assembly and the second valve assembly includes a valve casing supporting an inlet poppet valve, an outlet poppet valve, and a central opening located between the inlet poppet valve and the outlet poppet valve.
