HIGH PRESSURE VALVES
Series 20 >> Model H23
High Pressure — 3-Way Normally Closed Valve
PeterPaul’s model H23 has a dual operator valve that allows the same media control as a three way normally closed valve but at much higher pressure ratings than previously available. To function as a 3-way normally closed valve, operators must be alternately energized and de-energized. Pressure applied to the “IN” port must always be equal to or greater than the pressure in “CYL” port. Air and other non-corrosive gases, water and oil.
• Precision stainless free floating plunger.
• Kel-F pin sealing element.
• Orifice guides the sealing pin for near perfect alignment.
Note: This valve also available as an operator. Refer to following page.
