Instrumentation Manifold Valves are engineered for reliable isolation, calibration, and venting of pressure instruments in demanding process applications. Designed with compact structure and precision machining, these manifolds ensure accurate pressure measurement and safe operation in high-pressure and corrosive environments. Available in 2-way, 3-way, and 5-way configurations, they integrate multiple valve functions into a single block, reducing leakage points and simplifying installation.
High-quality stainless steel construction for corrosion resistance
Available in 2-way, 3-way, and 5-way manifold designs
Compact design reduces weight and leakage risks
Rated pressure up to 6000 psi (410 bar) or higher on request
Precision NPT, BSP, or tube connections
Leak-tight performance with PTFE/Graphite packing options
Compatible with transmitters, gauges, and differential pressure instruments


Stainless Steel Needle Valves are designed for precise regulation and secure shut-off of liquids and gases in instrumentation and industrial process systems. With a fine-threaded stem and conical seat, these valves provide accurate flow adjustment and bubble-tight sealing, even under high-pressure conditions. Manufactured from high-grade stainless steel, they offer excellent corrosion resistance and long service life in demanding environments.
Material: SS316 / SS304 stainless steel for durability and corrosion resistance
Pressure rating: Up to 6000 psi (414 bar) or higher upon request
Temperature range: -65°F to 450°F (-54°C to 232°C) with PTFE packing, higher with Graphite
End connections: NPT, BSPP, BSPT, or tube fittings (1/8″ to 1″)
Compact and rugged design for space-saving installation
Leak-tight performance with metal-to-metal or soft seat options
Panel mounting and inline mounting available
Stainless Steel Ball Valves are compact, quarter-turn shut-off valves engineered for reliable isolation in high-pressure fluid and gas systems. Despite their small size, these valves are designed to withstand working pressures from 1000 psi up to 6000 psi, making them suitable for demanding industrial, hydraulic, and instrumentation applications. The high-grade stainless steel body provides superior corrosion resistance, while precision-machined ball and seats ensure tight sealing and smooth operation.
Pressure rating: 1000 psi to 6000 psi depending on size and model
Material: SS316 / SS304 stainless steel for strength and corrosion protection
Size range: 1/4″ – 1/2″ (DN6–DN15) compact design
End connections: NPT, BSPP, BSPT, or tube fitting options
Seats & seals: PTFE or reinforced options for chemical compatibility
Operating temperature: -20°C to +200°C (depending on seat material)
Compact, lightweight body for installation in limited spaces
Quick quarter-turn operation with lever or T-handle options
Designed for bubble-tight shut-off and long service life


Stainless Steel Tube Fittings are precision-engineered connectors designed to provide secure, leak-free performance in instrumentation, hydraulic, pneumatic, and process applications. Manufactured from corrosion-resistant stainless steel, these fittings deliver reliable sealing under high pressure and extreme temperature conditions. With double ferrule or single ferrule designs, they ensure vibration resistance and easy installation without the need for welding.
Material: SS316 / SS304 stainless steel for excellent corrosion resistance
Pressure rating: Up to 6000 psi (414 bar) depending on size and design
Connection sizes: 1/16″ to 2″ (metric and imperial sizes available)
Types available: straight, elbow, tee, cross, bulkhead, unions, reducers, caps & plugs
Double ferrule and single ferrule designs ensure secure, vibration-resistant sealing
