Samson Valve Spares and Repair Kits

Samson valve spares and repair kits are designed to restore precision performance, maintain process integrity, and extend the operating life of your control valves. Each kit contains high-quality, genuine Samson components built to exact OEM standards, ensuring every replacement part performs identically to the original.

Available for both globe and control valve types, Samson valve repair kits typically include valve seats, plugs, seals, gaskets, diaphragms, and stem guides — all precision-engineered to deliver leak-free operation and accurate flow control. Whether performing scheduled maintenance or an emergency repair, these kits provide everything required to return your Samson valve to full working condition with minimal downtime.

Available for the following valve types: 3241, 3244, 3246, 3248, 3251, 3321, 3510, 251GR, 3254, 3256

Samson Self-Operated Regulator Spares and Repair Kits

Samson self-operated regulators are widely used for pressure, temperature, and differential control in steam, gas, and liquid applications. To maintain their precise regulation performance over time, genuine Samson regulator spares and repair kits are available to replace worn or damaged components. These kits are specifically designed for seamless compatibility with Samson’s leading self-operated models, including the Type 240, 241, and 242 series.

Each repair kit is assembled with high-quality OEM parts such as diaphragms, seals, gaskets, springs, and internal trim components — all manufactured to the same tolerances and materials as the original assemblies. This ensures stable pressure control, leak-tight performance, and reliable operation under demanding process conditions.

Available for the following self-operated regulator types: 2405, 2406, 2412, 2417*

Samson Actuator Spares and Repair Kits

Samson actuator spares and repair kits are designed to maintain the precision, responsiveness, and reliability of Samson pneumatic and electric actuators. These kits contain genuine replacement components engineered to the exact specifications of the original units, ensuring seamless fit and consistent performance in control valve assemblies.

Actuators play a vital role in valve automation and control. Over time, continuous operation and environmental exposure can cause wear to seals, diaphragms, and internal components. Samson actuator repair kits make it easy to restore smooth operation and eliminate common issues such as air leaks, sluggish movement, or reduced control accuracy.

Available for the following actuator types: 3271, 3277, 2413
