PHX Series Hydraulic and Electrohydraulic Actuators
Brand: Schrader BellowsSchrader Bellows Series PHX actuators can be customized to meet your exact specifications for NFPA interchangeable hydraulic cylinders with valve manifolds, integral feedback devices, or both!
Schrader Bellows Series PHX actuators combine the rugged Schrader Bellows PH-2 Series cylinders with the following:
- Bolt-on or Integral Manifolds for direct mounted Servo, Proportional or Industrial NFPA Hydraulic Valves. A custom steel transfer tube is provided between the valve manifold and the opposite cylinder end cap.
- Linear Displacement Transducer (LDT) or Linear Resistance Transducer (LRT) provide precise digital or analog position (or velocity) feedback.
Series PHX Linear Actuators are specifically designed to meet today’s demand for readily available, low cost linear actuators.
Features- Tri-Lip rod seal for positive no-leak sealing and increased machine productivity
- Universal Piston with 4 seal options permits easy in-field seal style change
- Every cylinder is individually tested to assure reliability
- Eighteen month warranty
- Bolt-on gland retainer for ease of maintenance
- Hi-Load piston is standard
- Cylinder body seal grooves and high-strength tie rods ensure trouble-free performance even in severe applications
- Floating cushions with float-check action and positive metal-to-metal seal
