Enhanced Control with the P75 Actuator for Diaphragm Valves
Precision, reliability, and ease of automation remain at the forefront of process industries — and the P75 actuator offers all three when integrated with diaphragm valves. Developed by KDV Flow, the P75 pneumatic actuator is engineered to deliver consistent valve operation in demanding environments.
Common issues in fluid handling such as inconsistent closure, slow actuation, and manual adjustment errors can lead to process inefficiencies or safety concerns. The P75 addresses these by offering a compact, responsive actuator compatible with various diaphragm valve bodies.
With decades of valve design and manufacturing experience, KDV Flow continues to offer purpose-built solutions backed by in-house engineering and global service capabilities — including diaphragm valve options for harsh and corrosive systems.
Specifications & Compliance of the P75 Actuator
Built to operate with diaphragm valves from DN15 to DN150, the P75 actuator is dimensionally aligned with EN558-1 Series 1 standards. Its design supports both weir and straight-through body configurations depending on the media requirements.
Key specifications include:
- Pressure rating: up to 10 bar operating pressure
- Temperature range: -10°C to 80°C (standard configuration)
- Material compatibility: available with options for chemically resistant linings such as EPDM or FKM diaphragm material
- Compliance: ISO 5211 mounting standard, with CE conformity on request
This actuator is tailored for industrial use, particularly in installations where consistency and automation readiness are paramount.
Where the P75 Excels: Industry Use Cases
The P75 actuator integrates seamlessly into systems across:
- Chemical processing — managing aggressive media with consistent sealing
- Pharmaceutical production — where sterile handling and repeatability are essential
- Water and wastewater treatment — ensuring accurate flow regulation under varied load cycles
For many of these environments, rubber-lined diaphragm valves are commonly paired with the P75 to enhance resistance to abrasion and provide reliable sealing. In these contexts, it delivers advantages such as reduced manual intervention, fast cycle times, and long-term service intervals.
Material Integrity and Design Efficiency
The P75’s body construction supports robust service conditions. Corrosion-resistant exterior finishes and internal sealing components make it suitable for clean room and aggressive service environments.
The compact pneumatic chamber is designed for optimal air consumption while delivering consistent actuation force. The actuator interfaces easily with standard control tops or positioners, supporting both feedback and modulation requirements.
KDV’s diaphragm valve range — when paired with the P75 — benefits from reduced torque requirements and low stress on diaphragms, extending their service life and reducing overall lifecycle costs. Explore more on our actuation products to see how the P75 fits into your broader system architecture.
P75 Actuator – Common Questions Answered
Q1: What makes the P75 actuator ideal for corrosive applications?
Its housing is built with chemical-resistant coatings and interfaces seamlessly with diaphragm valves fitted with appropriate linings such as PTFE or EPDM, reducing corrosion risk in harsh environments.
Q2: Can the P75 be automated for use with smart systems or PLCs?
Yes. The P75 supports direct mounting of control modules and sensors, including feedback switches and positioners compatible with most PLC and SCADA environments.
Q3: How does this model compare to earlier generation actuators?
The P75 features a lighter body, improved actuator stroke range, and lower air consumption, providing greater energy efficiency and faster response times.
Q4: Are replacement parts and linings available globally?
Yes. KDV maintains stock availability through regional hubs and authorised distributors, ensuring access to diaphragms and control accessories worldwide.
Q5: What customisation options are available for this actuator?
Custom stroke limits, position indicators, and material finishes can be specified based on application needs. Dual-acting and spring-return configurations are both available.
