How It Works
• two-way direct acting piston valves with stainless steel internals and Teflon® seats ensure reliable field proven performance.
• used for inlet valves on the NHL 200 to 600 and purge exhaust valves for all models.
• pneumatic actuators ensure precise proportional control and a bubble tight seal.
• rugged stainless steel disk construction and Teflon® seats combined with a low pressure drop design.
• used for inlet valves on the NHL 800 and larger.
• stainless steel spring return check valves provide worry-free operation and minimal maintenance.
• lift style check valves used on the NHL 200 to 600 and wafer style check valves used on the NHL 800 and larger.
• purge flow is field adjustable with this precision valve with visual setting indication.
• allows the operator to easily adjust the purge flow to match the operating conditions for optimal energy savings.
• these specially designed exhaust mufflers minimize the noise of depressurization and purge exhaust while also minimizing back pressure.
• the high flow design reduces blockage extending service life.
