Siemens · Valves & Process Control

Description  The Siemens 274-03168 is a 2-way Flowrite™ control valve with a 1-1/4" F x F connection designed for modulating control of steam and hydronic systems. Featuring a Cv of 16 and equal percentage flow characteristic, it provides precise regulation in HVAC and industrial applications. Equipped with a spring return electro-hydraulic actuator rated at 258 in-lb and powered by 24 VAC, it supports proportional control via 0–10 VDC or 4–20 mA signals.   Technical Specifications  Condition New/Never Used Surplus Brand Siemens Category HVAC Control Valves Part Number 274-03168 Subcategory 2-Way Control Valves Valve Type 2-Way, Normally Open Connection Size 1-1/4" F x F Flow Coefficient (Cv) 16 Flow Characteristic Equal Percentage Trim Material Bronze Actuator Type Spring Return Electro-Hydraulic Actuator Torque 258 in-lb Control Signal 0–10 VDC / 4–20 mA Supply Voltage 24 VAC Power Consumption 14 VA Stroke 3/4" Run Time 30 Seconds Powered Spring Return Time 15 Seconds Media Saturated Steam, Water, Glycol (Up to 50%) Fluid Temperature Range 20°F to 250°F (-7°C to 120°C) Ambient Temperature Range 5°F to 130°F (-25°C to 150°C) Weight Approx. 8 kg     Information About 274-03168 The 274-03168 is part of Siemens’ Flowrite valve series, engineered for accurate flow modulation in heating, cooling, and process control systems. This normally open, 2-way valve incorporates bronze trim and female threaded (F x F) connections for durability and straightforward installation. Designed for service with saturated steam, water, and glycol solutions up to 50%, it operates within fluid temperatures from 20°F to 250°F (-7°C to 120°C). The integrated spring return electro-hydraulic actuator ensures fail-safe positioning with a 15-second return time and supports proportional control signals for seamless integration into building automation systems. Key Features: 2-Way Normally Open Design: Provides reliable flow control with fail-safe spring return operation. Equal Percentage Flow Characteristic: Enables stable modulation across varying load conditions. Cv 16 Flow Capacity: Supports balanced control in medium-capacity HVAC and steam systems. Electro-Hydraulic Actuator (258 in-lb): Delivers strong, precise valve positioning. Proportional Control Inputs: Accepts 0–10 VDC and 4–20 mA signals for BAS compatibility. Fast Response Time: 30-second powered stroke with 15-second spring return. Wide Media Compatibility: Suitable for saturated steam, water, and glycol solutions up to 50%. Temperature Tolerance: Fluid temperature range from 20°F to 250°F for flexible application use. The 274-03168 delivers the reliability and precision required for proportional flow control in HVAC and steam regulation systems.
