Tejas precision products is a manufacturer of highly reliable on-off control valve systems for process control and instrumentation packages of modern process industry. The actuator systems have been specifically designed to meet the stringent specifications of petroleum, petrochemical and allied chemical industries. All equipment are designed and selected with optimum safety factors to en- sure adequate working margins. All are made from properly tested high quality corrosion resistant materials and finished, ensuring and minimum wear in hostile environments encountered. All the materials and processes of production are 100 percent inspected at every stage to offer good quality, prompt delivery and best price. The company offers accessories like limit switches, solenoid valve, manual over-ride, cable gland, etc. It provides triple tier sealing arrangement across the stem to prevent any leakage: a primary seal between body and stem effected by a ptfe "0" ring; a second carbon filled gland packing and stainless steel gland material provides flexibility and rigidity at the top of the stem to prevent any leakage across the stem length; and thirdly, two belleville spring washers live load and stem and adjust for any wear or expansion and con- traction due to temperature fluctuations. A slit nut at the top prevents unnecessary movement of sealing rings and completely eliminates gland leakage problems associated with rising stem gate/globe valves.
