Reciprocating Compressor Valves
Ring, mesh and poppet valves for compressor OEMs and plant operators. We choose the type, materials, lift and springs to suit your compressor, gas and operating conditions.
Ten valve models in three designs: ring, mesh and poppet. Which one fits depends on your compressor, gas and operating conditions.
We select the valve from your machine configuration, gas, pressures, temperatures and speed.

RONDER™ is the global brand of Wenzhou Ronder Compressor Valve Technology Co., Ltd. We design and manufacture reciprocating compressor valves, choosing the valve type and configuration for each compressor, gas and duty. Our customers are compressor OEMs and industrial end users.
About RONDER
A Shandong coal-chemical plant's 4M40-150/80 CO₂ compressor ran WD mesh valves for 8,000+ hours without failure after a redesign. How the valves were selected and checked.
Fifth-stage 6MD32(3)-195/220 CO₂ compressor valves redesigned with WG valves and 30Cr13 plates; 8,000+ hours without failure.
Low-lift HK ring valves for the second stage of a hydrogen compressor: sealing design, valve-motion calculation and 8,000+ hours without failure.
Valves in four chloromethane compressors lasted from days to two months. How RONDER found the likely causes and redesigned them as WP valves, which now average 16,000 hours.
A 2009 customer letter records the replacement of valve springs and PEEK valves on GEMINI reciprocating compressors, a change from monthly to annual maintenance, and PEEK valve plate performance on hydrogen compressors.
A petrochemical plant reported piston ring service intervals of about two months. RONDER proposed material, joint and pressure-balancing changes for severe uneven wear.
A refinery replaced short-lived, heavily fouled compressor valves with RONDER valves using PEEK plates, 17-7PH springs and 3Cr13 seats. Recorded operating hours reached 5,520 and 2,136.
RONDER developed compressor valves for an international manufacturer's 1800 r/min model. The OEM accepted the revised design after reviewing the simulation results. Compressor production trials are ongoing.
A coal liquefaction plant in Inner Mongolia used RONDER replacement piston rings, rider bands and packing for imported hydrogen compressors, followed by valve refurbishment. Customer reports document the results and valve use on three compressor models.

Where available, include the compressor manufacturer and model, required parts and quantities, and the gas, pressure, temperature and speed. Attach any drawings or photos you can share. You can contact us before all the details are available.
Compressor manufacturer, model and configuration; gas composition; pressure and temperature; speed; operating conditions; and any failures or problems you have seen. You may start with the information available.
Yes. Provide the information available, and we will identify any additional data needed.
We supply OEMs of large reciprocating, high-pressure and special-gas, and diaphragm compressors, as well as chemical and process plants that run them.
We also supply guide rings, rider rings, piston rings, oil scraper rings and piston rod packing assemblies.
We work from your compressor configuration, gas composition, pressure, temperature, speed and operating conditions. Once these are known, we fix the design, materials and configuration.
