Pressure Relief Valve

Pressure relief valve is one of our valve fitting types performs as a safety mechanism to prevent accidents or explosions in extremely high-pressure environments. Teamco provides pressure relief valve which compliant to API 6D in oil&gas application. Pressure relief valves are components used in hydraulic systems to limit fluid pressure to a specific set level. Materials we produce include stainless steel, carbon steel and alloy. The pressure relief valve feeds the excess flow back to the tank or out of the system when the set level is reached. It closes when the level returns back to normal. We provide ODM or OEM pressure relief valves, export to Europe and America. These pressure relief valves are used in oil&gas, industrial fluid control, liquid processing, etc. All specifications we produce are based on customer designs and requirements.

  • Sealant Injection Fitting - Custom Injection Fitting fits Custom Specifications
    Sealant Injection Fitting

    Teamco provides Sealant injection fittings based on customer specifications to be used as valve backup sealing in applications of valve piping or industrial fluid control. The sealant injection fittings are primarily a one-way check valve designed to provide for the periodic injection of lubricant/ sealants into pipeline valves. The materials we produce include stainless steel, carbon steel and alloy. In Oil& Gas segment, most ball valves has two sealant injection fittings, generally one is located at the stem area and the other at the seat area. These sealant injection fittings only function for emergency or backup sealing when soft sealing rings damage by accident. In this situation the sealant is injected to prevent stem leakage and temporarily seal the valve. Our injection fittings apply to API requirements and are exported to worldwide oil&gas and industrial customers, such as USA, Canada, Italy and Malaysia, etc. All the specifications we produce are based on the customer designs. When receive the customer request, our product development team will be able to recommend or provide the best solutions fit customer’s diversified applications.

  • Spring Loaded Safety Relief Valve - Hydraulic Safety Relief Valve fits Customer Applications
    Spring Loaded Safety Relief Valve

    Teamco provides spring loaded safety relief valves used in applications of limiting pressure in an entire system such as pipelines and valves. The operation type is direct-acting or direct-operated. When set opening pressure is reached, the spring loaded element triggers and opens for venting the excessive pressure. The pressure adjustment range of our spring loaded safety relief valve is 20~25 kgs/cm². We produce both stainless steel 316 and carbon steel 4140. Specifications are based on customer requirements. Our spring loaded safety relief valves are used in a wide range of commercial hydraulic control, industrial fluid control, oil & gas processing, etc. We design, manufacture and serve diversified customer segments worldwide. Let us know your requirements and applications, our sales and engineering team will help fulfilling your needs.

  • Check Valve Fitting - Custom Check Valve Fitting in Stainless Steel or Carbon Steel
    Check Valve Fitting

    Teamco provides Check Valve Fitting in SS316 and AISI4140 (zinc plated) materials for hydraulic applications such as Oil&Gas piping system and industrial fluid control. The movable part to block the flow is a ball loaded by a spring to keep it shut. The check valve fitting allows flow moves in one direction and blocks the flow in the reverse direction. It means one-way flow, non-return or backflow prevention. It requires a higher pressure on the input side than the output side to open. When the pressure is higher on the outlet side (or is not high enough on the input side), it will close. Teamco produce check valve fittings in custom specifications and has been exporting to USA, Italy and other countries in South-East Asia such as Malaysia. They are applied to API applications in pressure class ranges 1,000 ~ 20,000psi. For achieving diversified applications and industry standards, materials and constructions can be produced according to customer designs.
