Key Parameters & Specifications The following parameters are typical for the EZH and EZHSO series. Category Parameter Name Description & Typical Values General Specifications Actuator Type Electric, Spring-Return (EZH) or Electric, Non-Spring Return (EZHSO) Valve Style Globe Valve or Angle Valve body Valve Size 1/2" to 2" (DN 15 to DN 50) - Common for HVAC applications. End Connections Screwed (NPT) - Standard. Flanged or other connections may be available. Electrical Data Input Signal & Power 20 to 135 VAC, 50/60 Hz; 2-wire system. The voltage level modulates between a minimum (e.g., ~30V = 3 psi = closed) and maximum (135V = 15 psi = open) to command the position. Power Consumption Typically 5-6 VA (running). Valve Body Body Materials Bronze or Cast Iron - Standard. Ductile Iron and Stainless Steel may be options. Pressure Rating Varies by body material and size. e.g., Bronze: 200-400 psi WOG. Temperature Limits Standard: -20°F to 250°F (-29°C to 121°C). High-Temp: Up to 350°F (177°C) with special packing. Trim & Flow Flow Characteristic Equal Percentage - Standard, ideal for HVAC water systems with varying pressure drops. Leakage Class Class IV (with soft seat) - Standard, providing tight shut-off. Performance Stroke Time Typically 30 to 60 seconds for full travel (depending on valve size). Fail-Safe Action (EZH only) Fail-Closed or Fail-Open - Field-reversible. Enclosure Rating NEMA 1 (Standard), NEMA 4X (Weatherproof) - Optional.
