HPD Series
Product Introduction
High Reliability & Long Service Life
The surface treatment employs epoxy electrostatic powder coating, providing exceptional adhesion and corrosion resistance. The diaphragm utilizes a specialized molding process with burst strength exceeding 22 kg/cm², significantly enhancing overall operational lifespan.
High Output Force
The molded diaphragm and cold-stamped diaphragm housing withstand elevated pressures, enabling maximum thrust generation.
Rigid Connection
The clamp-style stem connection reliably transmits motion while facilitating installation. By eliminating linkage mechanisms, it prevents positioning inaccuracies caused by connection backlash.
Excellent Linearity
The molded diaphragm moves within the diaphragm chamber with minimal change in effective area during travel, ensuring superior linear performance.
Responsive Operation & Fast Response
The actuator utilizes direct air pressure on the diaphragm for immediate linear movement without lag. With minimal diaphragm inertia, it rapidly responds to pressure signal variations, making it ideal for applications requiring frequent cycling.
Wide Applicability
Five sizes of direct-acting and reverse-acting actuators enable diverse applications. With customizable spring ranges, adjustable travel stops, and optional handwheel assemblies, they accommodate virtually any control valve requirement.
