Instrumentation Valves – Tragency Middle East

Small valves used within pneumatic and hydraulic control circuits to direct, isolate, or protect flow — as distinct from the larger process valves these systems actuate.

Product Description

BIFOLD — Ball Valves — Quarter-turn valves that use a rotating ball to start, stop, or isolate flow.
BIFOLD — Check Valves — Valves that permit flow in one direction only, preventing backflow.
BIFOLD — Fire Safe Valves — Valves designed to maintain a safe seal even when exposed to fire.
BIFOLD — Flowline Pilot Valves — Pilot-operated valves that control pressure or flow within a flowline circuit.
BIFOLD — High Pressure Gas Solenoid Valves — Electrically operated valves rated for high-pressure gas service.
BIFOLD — Hydraulic Pilot, Interface, Mechanical Valves — Valves operated by hydraulic pilot signal or mechanical actuation to control hydraulic circuits (e.g. FP15 series).
BIFOLD — Hydraulic Solenoid Valves — Electrically operated valves for switching hydraulic flow.
BIFOLD — Medium Pressure Ball Valves — Quarter-turn ball valves rated for medium-pressure service.
BIFOLD — Medium Pressure Needle Valves — Needle valves for precise flow throttling at medium pressures.
BIFOLD — Needle Valves — Valves using a tapered needle for fine, precise flow control.
BIFOLD — Pneumatic Mechanical Valves — Manually or mechanically actuated valves for pneumatic circuits (e.g. BXS(mech), SPR16(mech) series).
BIFOLD — Pneumatic Pilot Valves — Pilot-operated valves that switch pneumatic circuits in response to a control signal.
BIFOLD — Pneumatic Solenoid Valves — Electrically operated valves for switching pneumatic (air) flow.
BIFOLD — Pressure Sensing Valves — Valves that respond automatically to changes in system pressure.
BIFOLD — Quick Exhaust Valves — 316 stainless steel valves for severe environments that rapidly vent gas, air, inert gas, or low-pressure liquid to atmosphere to speed up an actuator’s release stroke.
BIFOLD — Relief Valves — Automatically open once system pressure exceeds a set threshold, protecting equipment from overpressure.
BIFOLD — Shuttle Valves — 316 stainless steel three-way “OR” valves that automatically pass through whichever of two pressure sources is higher, for gas, air, or liquid media.
BIFOLD — Subsea Needle Valves — Needle valves engineered for precise flow control in subsea hydraulic systems.
BIFOLD — Subsea Pilot, Interface, Mechanical Valves — Pilot-operated, interface, and mechanical valves built for subsea control systems in offshore oil and gas.
BIFOLD — Subsea Shuttle Valves — Shuttle valves engineered for subsea hydraulic redundancy applications.
BIFOLD — Subsea Solenoid Valves — Electrically operated valves (FPS01/FPS10/FPS15 series) for deep-water subsea control systems.
BIFOLD — Thermal Relief Valves — The VRT series: protects trapped fluid volumes from pressure build-up caused by temperature rise.

Fire Safety Valves — Fusible fire safety valves used in onshore/offshore oil and gas production shutdown systems since 1989, in configurations for different pressure/temperature ratings.
Flow Control Valves — Uni-directional valves with a bypass-check feature for rapid free flow one way, or bi-directional needle valves that regulate actuator speed by controlling flow/pressure both ways.
High Flow Exhaust Valves — Pilot-operated, 2-way normally-closed directional control valves with automatic pressure sensing/relief, for accurate high-volume exhaust flow control.
Logic Valves — Compact poppet valves (1½”/2”, 1-3 port exhaust), SIL 3 capable, for low-pressure (up to 10 bar) instrumentation logic functions.
Needle Valves — Valves using a tapered needle element for fine, precise flow adjustment.
Pilot and Mechanical Valves (PPV series) — Compact stainless steel low-pressure pneumatic/hydraulic valves offering high flow capacity for multi-directional flow.
Rotork — Spool Solenoid Valves — Electrically operated spool valves for pneumatic actuators: RNSV (NAMUR connection) and RPSV (threaded pipe ports).
