New Design Features:
• Interior Design – more efficient flow and operation
• Dual Locking Nuts – vibration resistant for setting maximum pressures
• New Spring Material – more resistant to fatigue, powder paint resists rusting
• Piston – large diameter, more strength and contact area for shifting alignment
• Discharge Nipple – sealing o-ring has been moved to the lower part of the thread, increases hydro strength and fitting strength
• Shutter Valve – hex design, less contact area for smooth shifting (prevents binding). larger size, longer life and more positive shifting
