Product Overview

The Siemens C73451-A430-B33 Double Acting Piezoelectric Pneumatic Valve Block is designed for reliable pneumatic pressure control within compatible Siemens SIPART PS2 electropneumatic valve positioners. This replacement component regulates compressed instrument air delivered to double-acting pneumatic actuators, supporting accurate valve positioning, responsive actuator movement, and dependable performance in industrial automation and process control systems.

Manufactured by Siemens, the C73451-A430-B33 is a pneumatic valve component used in SIPART PS2 positioners, including compatible 6DR4 and 6DR5 series models. The original C73451-A430-B33 component has been superseded by the Siemens C73451-A430-D81 pneumatic block replacement kit, which includes the pneumatic block, sealing components, and mounting screws. Designed for industrial valve positioner maintenance, equipment servicing, and pneumatic control system repairs, this component is suitable for manufacturing, chemical processing, oil and gas facilities, power generation, and industrial fluid control applications.

// FAQs

Questions about this part?

Our engineers can confirm fit before you order. Contact support.

How do I find the right part for my system?

Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.

Can you help me size a pump or valve for my application?

Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.

Can you cross-reference a discontinued part?

Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
