The 2 Valve Manifold H Type Flange to Flange is designed for use in the oil and gas industry to connect impulse lines and transmitters. Its simple two-valve configuration allows operators to perform essential tasks such as blocking, bleeding, and calibrating static pressure transmitters or gauges with ease. This design ensures accurate and reliable measurement while minimizing the risk of leaks or process interruptions.

The H Type manifold features a metal-to-metal body and bonnet seal, which provides a secure seal under high pressure and temperature conditions, eliminating the need for O-ring seals. The valves are designed with a self-centering, non-rotating tip to provide consistent positive shutoff and reduce wear on the packing. The stem includes a back seat for added safety, and a removable T-handle ensures smooth operation with low torque. A dust cap protects the stem from contamination, and rolled threads improve durability and ease of operation.

These manifolds are manufactured to meet ASME B16.34 standards for pressure-temperature ratings and are type tested to MSS-SP-99. They have a standard working pressure of 6000 PSI, with higher pressures available upon request. Materials can be supplied in accordance with NACE MR 01 75, and temperature ratings range from -50°C to 230°C, or up to 500°C with graphite. Every valve is factory tested for leakage and performance, and heat code traceability ensures quality and reliability. 

Hex Reducing Couplings Female NPT are precision pipe fittings designed to connect two pipes of different sizes while maintaining a secure, leak-tight connection. The female NPT threads provide a tapered seal that ensures a tight fit when connected to a male NPT thread, making them suitable for high-pressure systems up to 10,000 PSI. The hex shape of the coupling allows for easy tightening with standard tools, providing both convenience and reliability during installation.

Reducing couplings are specifically used when there is a need to transition between different pipe sizes in a system, allowing for flexibility in design and modification of existing pipelines. They help maintain proper flow rates, pressure, and system integrity without the need for custom fittings. This makes them essential in oil and gas systems where varying pipe sizes are common.

These couplings are manufactured from high-quality materials and are compliant with recognized standards, including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, ensuring consistency, traceability, and durability in demanding applications. Hex Reducing Couplings Female NPT are ideal for situations where space is limited and a reliable connection between different pipe sizes is required, supporting both operational safety and system efficiency.

Square Body Needle Valves Male x Female are engineered for precise flow control and isolation in high-pressure piping systems. The square body design provides a rigid, compact structure that allows for stable mounting, easy wrench access, and alignment during installation. The male and female threaded ends enable secure connections to instrumentation, piping, or process equipment, ensuring leak-tight operation.

These valves are used in oil and gas applications such as connecting impulse lines, controlling flow to pressure transmitters, and isolating instrumentation for maintenance or calibration. The square body allows for easy integration into compact manifolds or tight piping layouts where space and alignment are critical.

Constructed to meet ASME B16.34 and MSS-SP-99 standards, the valves are rated for standard working pressures of 6000 psi, with optional higher-pressure ratings available. They operate effectively over a wide temperature range and are factory-tested for seat and packing leakage, ensuring reliable, consistent performance in demanding field conditions.

The HDI 1522 Choke Position Indicator System is an electronic instrument designed to accurately measure and display the position of choke valves used in oil and gas production. Choke valves regulate the flow of oil, gas, or water from wells by adjusting the degree of restriction in the pipeline, which directly affects pressure control and production rates. The 1522 system provides highly precise position readings in one percent increments, ranging from fully closed (0%) to fully open (100%), enabling better management of well performance and enhanced safety.

This system uses solid-state electronics to convert mechanical valve movement into electronic signals via various potentiometer types—including linear, rotary, and retractable options—making it adaptable to a wide variety of choke valve designs and configurations. The position data is presented on a four-inch liquid crystal display that combines a numeric readout with a linear bar graph, allowing clear and immediate visualization of the choke’s exact position. The display is engineered for visibility from distances up to fifteen feet, suitable for typical field environments.

Powered by an internal, field-replaceable battery with approximately one year of continuous operation, the 1522 system minimizes maintenance requirements and eliminates the need for complex wiring. It also offers optional analog output signals, such as 4-20 mA or 0-1 V, enabling seamless integration with plant control systems, programmable logic controllers, data acquisition systems, or remote display units for centralized monitoring and automation.

The enclosure is constructed from UV-stabilized, impact-resistant polycarbonate and PBT alloy materials to ensure durability in harsh outdoor conditions. It is rated to operate reliably within a wide temperature range from -40°F to 176°F (-40°C to 80°C). The internal electronics are protected by a gasket seal to prevent dust and moisture ingress, maintaining performance and longevity.

Installation flexibility is enhanced through support for cable lengths up to 1,500 feet, allowing the gauge to be mounted in the most accessible or secure locations. Multiple sensor housing options and connector orientations simplify field installation and reduce the need for onsite customization, helping to minimize downtime and installation costs.

The 1522 Choke Position Indicator System delivers accurate, real-time choke valve position information in a robust, easy-to-install package. Its reliable performance, flexible integration capabilities, and low maintenance design support improved flow control, safer operations, and optimized production.

The Check Valve Poppet Type with 3/8" NPT tube ends is a compact valve designed to allow flow in one direction while preventing reverse flow in hydraulic, pneumatic, and industrial systems. It features a spring-loaded poppet mechanism that opens when forward pressure exceeds the cracking pressure and closes immediately when flow attempts to reverse, ensuring reliable protection for pumps, compressors, and other critical equipment.

Rated for a standard working pressure of 6,000 psi, with optional higher-pressure ratings up to 10,000 psi, this valve is suitable for demanding applications in oil and gas, chemical processing, instrumentation, and general industrial environments. The 3/8" NPT tube ends provide secure, leak-tight connections and easy integration into medium-diameter piping or tubing systems.

The poppet design minimizes pressure drop while delivering fast response and tight sealing, reducing the risk of backflow and system inefficiency. Built from durable materials such as stainless steel, Duplex, Super Duplex, Hastelloy, Inconel, or Monel, the valve offers long service life even in corrosive or high-pressure conditions. Factory testing ensures each valve meets standards for cracking and reseal performance, with heat code traceability for full material verification.

This type of valve is particularly effective in applications requiring precise flow control, compact installation, and reliable one-way operation, making it an essential component for maintaining system integrity and protecting valuable equipment.
