Product name：Low-maintenance control valve with pneumatic actuator

Product introduction：

Low-maintenance control valve to DIN/EN, with flange, linear or equal percentage control characteristic selectable between Kvs values 0.1 and 630 m³/h, closing pressure max. 40 bar, all internal parts can be replaced easily without special tools, including the base on both sides, standard noise reduction with two-stage pressure relief by means of parabolic cone and perforated cage, with pneumatic actuator.

Application：

1. Hot water heating equipment

2. Air conditioning equipment

3. Boiler feed water

4. Boiler circulation system

5. Chemical industry

6. Process technology

7. Heat recovery equipment

8. Sugar industry

Advantages：

1. Noise reduction through two-stage pressure relief (integrated as standard)

2. Anti-cavitation measures through the combination of perforated cage and perforated cone.

3. Easy to match the respective regulation task by combining different cone shapes (equal percentage or linear) with different seat diameters

4. Different spindle seals, optionally with maintenance-free PTFE top sleeve (< 250°C) or adjustable graphite gland (450°C)

5. Various mounting options possible through exposed drive column (mounting position regulator, solenoid valve, limit switch, etc.)

6. Electric actuator with parameterized control system: continuous or 3-point, integrated in process control system, with 0/2-10 V or 0/4-20 mA signal and available in various sizes up to 25 kN

7. Easy maintenance, internal parts can be replaced without special tools by loosening the cover bolts

8. High-quality internal parts made of stainless steel (1.4571), with high stability and chemical resistance

9. Labyrinth cover seal on both sides, low risk of leakage
