Replacement diaphragm EPDM for 2/2-way solenoid valves G 3/8, G 1/2 and G 3/4 - E.MC

The diaphragm is the wear part of a diaphragm solenoid valve. This EPDM seal kit restores ZS series valves with G 3/8, G 1/2 (DN 16) and G 3/4 (DN 20) ports. EPDM is intended for air and hot water up to +120 °C and replaces the NBR diaphragm where the water gets too hot.

Advantages

• One diaphragm for three port sizes: G 3/8, G 1/2 and G 3/4.
• Fits valves with brass and with stainless steel bodies.
• Lets you switch to a different seal material when the medium changes.
• EPDM material, media temperature -10 to +120 °C.

Applications

• Scheduled maintenance when the valve no longer seals tight or switches with a delay.
• Converting an installed valve to a different medium or temperature range.
• Spare parts stock for systems running several valves from G 3/8 to G 3/4.
