Jetmark Industries

We manufacture and export technically advanced, high quality auto valves, automotive valves and fittings for critical services in oil, gas, petro-chemicals, fertilizers, power generation and many other industrial applications. Our pipeline & instrumentation valves, manifolds and fittings are offered in various materials of your choice, incorporating a wide range of process connections. We guarantee prompt delivery along with full conformation to relevant standard specifications for highest quality of products.

We manufacture valve guides that are made from two kinds of material:

• Grey Cast Iron
• CuZnAl-alloy

GREY CAST IRON of perlitic structure with high phosphorous content. The perlitic structure and the reticular phosphide distribution along with the good graphite formation give high wear resistance and improved running properties in poor lubrication condition. CuZnAl-alloy Guides are with excellent wear resistance and low coefficient of friction. Used for highest stressed guides. All our Cast Iron Guides are manufactured having minimum hardness of 93 HRB (200 BHN).

These valve seats are made from heat resistant and wear resistant high quality alloy steel and are manufactured with clear convenient identification marking and radius edges for easy installation. These seats will resist intense valve pounding and effectively dissipate heat for consistent valve sealing. These valve seats will increase in hardness during engine break-in period. See charts below for sizes.

Our valve seats are made from highly alloyed material and feature the following :

• Easy oversize identification by the part number
• Easy to machine with cutter and stone
• Resists severe pounding and dissipates heat better
• Work-hardens during running-in
• Radiused for easier installation
