Overview

This document details technical specifications, operating parameters, and control options for a broad range of Swiss-quality characterised control valves and globe valves used in water, steam, and industrial fluid systems. It covers valve types including characterised control valves, globe valves, ball valves, and butterfly valves, along with their actuators and control modes.

1. Characterised Control Valves

• Types and Control Modes: Available with 3-point and modulating control signals (AC/DC 24V, AC 230V, DC 0-10V, DC 2-10V). Actuators include options for normally closed (NC) or normally open (NO) operation, auxiliary switches, and running times from 9 to 150 seconds depending on actuator type.
• Pressure and Temperature Ratings: Internal thread valves rated up to 1600 kPa and 100°C; extended function valves up to 2700 kPa and 130°C; flanged valves PN6 to PN16 rated up to 120°C.
• Flow Parameters and Sizes: Valve diameters from DN 10 to DN 150+, flow coefficients (kvs) from 0.09 to 320 m³/h, with pressure drops typically between 350 and 1600 kPa.
• Special Features: Parameterisation of running times, control signals, stroke limits via PC-Tool or MFT-H device; low noise operation options with reduced max pressure drop (200 kPa); parallel control limitations for some valve types.

2. 6-Way Characterised Control Valves

• Modulating control with bus communication options.
• Internal thread Rp rated at 1000 kPa, temperature range +5 to +50°C.
• Flow coefficients from 0.25 to 1.3 m³/h, max pressure drop 100 kPa.

3. Large Characterised Control Valves (DN 65 to DN 150)

• Flanged valves with IP66/67 protection, operating temperature up to 120°C.
• Flow coefficients up to 320 m³/h, pressure drops up to 600 kPa.
• Control options include open-close, 3-point, and modulating signals with running times 35 to 90 seconds.

4. Electronic Pressure-Independent Characterised Control Valves

• Flanged PN16 valves, temperature range -2 to 120°C.
• Flow coefficients 8 to 45 l/s (28.8 to 162 m³/h), max pressure drop 340 kPa.
• Parameterisable control, position feedback, and running time via PC-Tool.

5. Globe Valves

• Standard Globe Valves: External thread (ISO 228) or flange (ISO 7005), PN6 and PN16, max 120°C, DN 15 to 150, kvs 0.63 to 320 m³/h, pressure drops 230-1600 kPa.
• Large Globe Valves: Flanged PN16 for DN 200 and 250, kvs 630 and 1000 m³/h, pressure drops 190-310 kPa.
• High-Temperature Globe Valves: For steam and water up to 150°C, pressure ratio ∆p/p1 < 0.4, pressure-balanced designs, 3-point and multifunctional actuators with modulating control.

6. Control and Parameterisation

• Valves support parameterisation of control signals, running times, stroke limits, and position feedback via PC-Tool or multifunctional devices.
• Actuators configurable as normally open or normally closed, with auxiliary switches.

7. Important Notes and Limitations

• Media compatibility includes water, water with glycol (up to 50% vol), and steam (with pressure ratio limits).
• Temperature limits must be respected; actuator installation restricted above 100°C.
• Parallel control not possible for some valve types.
• Low noise operation available with reduced max pressure drop.

8. Additional Valve Types and Specifications

• Globe Valves: Flange standards ISO 7005 PN 25 and PN 40, max temperatures 150°C to 200°C, DN 15 to 100, kvs 0.4 to 160 m³/h, pressure up to 2500 kPa.
• Ball Valves: Internal thread Rp and external thread G, DN 10 to 50, kvs 4 to 49 m³/h, pressure ratings up to 4140 kPa, operating temperatures 5°C to 110°C.
• Butterfly Valves: Flange standards ISO 7005 / EN1092-2 PN6, PN10, PN16, temperature -20°C to 120°C (glycol), DN 25 to 350, kvs 45 to 10900 m³/h, pressure up to 1200 kPa.

9. Actuators and Control Features

• Motorized and rotary actuators with IP54 to IP67 protection.
• Running times vary by valve and actuator type: 9 s to 150 s.
• Control signals include 3-point, 0-10V DC, 1-wire, and 2-wire systems, AC/DC 24V, and AC 230V.
• Spring return actuators provide fail-safe operation with return times typically under 75 s.

11. Recommendations and Best Practices

• Select valve and actuator combinations based on required flow rate, pressure, and temperature conditions.
• Ensure control signal compatibility with existing automation systems.
• Use spring return actuators for fail-safe applications.
• Verify pressure ratings and temperature limits for installation environments.
• Choose IP66/67 rated actuators for harsh environments requiring dust and water protection.
• Consult manufacturer support for product range and technical assistance.
