Forged first stage body with heat exchanging ribs for maximum thermal performance. Angled HP ports for optimal hose routing and fitting of transmitters. Forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation. Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
