Needle Valves

Product catalog summary

Overview
TECVAL specializes in manufacturing needle valves for various industrial applications, particularly in high-pressure and high-temperature environments. The document details different needle valve models, each designed for specific conditions and requirements.

Needle Valves

CP-01 Back-Seat Needle Valves: Suitable for high-pressure and temperature liquids, featuring metal-to-metal shut-off, stainless steel stems, and PTFE packing. Options include movable stem tips and automation through actuators.
CP-12 Back-Seat Angular Needle Valves: Similar to CP-01 but with an angular design, used in chemical plants and refineries.
CP-15 Integral Bonnet Needle Valves: Compact design for high-pressure or moderate vacuum service, featuring a body that incorporates the bonnet.
CP-20 Needle Valves for Severe Services: Designed for extreme conditions, offering high-pressure and temperature resistance with a solid design.
RG-90 Needle Valves for Gases: Ensures perfect closing and sealing for gases, featuring a double O-ring seal and no maintenance requirement.
AC-02 Needle Valves for Corrosive Fluids: Designed for highly corrosive fluids, featuring a double packing design for maximum leak-proof security.

Instrumentation Needle Valves

CP-04 Back-Seat Needle Valve (MxH): Designed to prevent water hammer, suitable for high-pressure and temperature liquids.
CP-06 Back-Seat Needle Valve (HxH): Similar to CP-04, used to insulate and protect instruments.
CP-09 Integral Bonnet Needle Valves (MxH): Compact design with optional positioner nut for instrument positioning.
CP-11 Needle Valve with Bridle for Pattern: Includes a bridle for pattern manometer, allowing free packing change in service.
CP-13 Needle Valve with Alignment Sleeve: Manufactured following DIN 16270 AR standard, featuring an alignment coupling for instrument positioning.
MULTIPORT: Multiport needle valve with three female exits.

Technical Specifications
Each valve model includes detailed technical data such as maximum pressure, temperature range, connection types, dimensions, orifice size, flow coefficient, and materials used. Common materials include brass, carbon steel, stainless steel AISI-316, and special alloys.

Multiport Needle Valves Overview
Designed for use with liquids under high pressure and temperature conditions, featuring a three-female-port system for simultaneous connection with other check or security elements. The back-seat design permits packing changes while the valves remain in service.
