Most valve failures are component failures — a worn seat, a corroded stem, a seized gearbox — not a failed valve body. Replacing a seat or an operator costs a fraction of replacing the whole valve, and it avoids the pipework disruption of a full valve changeout. G & A Valves International stocks spare parts and actuation packages so maintenance teams can rebuild and automate valves in the field.
Spare parts
Seats and seals
- Resilient seats in common compounds — EPDM, NBR, Viton (FKM), PTFE/RPTFE — for butterfly, ball, and check valves; seat profiles vary by model, so send your valve markings and we will confirm the right match
- O-rings and stem seals in standard compounds — tell us the compound or send the old seal and we will match it
Discs, balls, and closure elements
- Butterfly discs in industry-standard materials and coatings (e.g. ductile iron, stainless steel 304/316) — confirm availability for your valve model
- Ball valve balls and seats in stainless steel with PTFE/RPTFE seat sets — confirm availability for your valve model
- Check valve discs, plates, springs, and hinge pins — send your valve markings and we will confirm spares availability
Stems and hardware
- Stainless steel stems in common grades — confirm the grade you need with us
- Gearbox operators and lever handles with locking devices — confirm availability for your valve size
How to order parts: send the valve's original markings (manufacturer, model, DN size, pressure class) or photos of the nameplate and the failed component to [email protected]. We match parts to your installed base — where an exact match is not available, we will advise on the closest compatible option.
Actuation
Pneumatic actuators (rack-and-pinion)
- Torque range: a range of actuator torques to suit common valve sizes — tell us your valve size and line pressure and we will size the actuator
- Double-acting and spring-return (fail-safe) configurations
- Accessories: solenoid valves, limit switch boxes, filter-regulators, and positioners can be supplied with the package — confirm the accessories you need
- Standardized mounting interfaces (e.g. NAMUR) for straightforward actuator-to-valve coupling — confirm the interface on your valve
Electric actuators (quarter-turn)
- Torque range: a range of actuator torques to suit common valve sizes — tell us your valve size and line pressure and we will size the actuator
- Voltage: common voltages including 110/220 VAC and 24 VDC — confirm your supply voltage when ordering
- Duty cycle: on/off and modulating duty options — confirm the duty your application needs
- Accessories: local manual override, position feedback (4–20 mA), and fieldbus communication options — tell us your control system and we will confirm compatible protocols
Manual operators
- Lever handles, worm gearboxes with handwheel, and chainwheel options for elevated valves — confirm the operator type and size range with us
Actuated valve packages: we mount, couple, and calibrate the actuator to the valve before shipment, function-test the assembly, and ship it ready to bolt in — ask us about our pre-shipment testing and limit-switch verification procedure.
Why source parts and actuation from GA Valves
- One supplier for the whole valve: body, trim, spares, and automation from a single purchase order.
- Assembly and testing: actuated packages arrive tested and calibrated — not a box of parts to figure out on site.
- Training: hands-on training in actuator mounting, calibration, and troubleshooting, so your team handles future automation in-house.
- Documentation: torque data, wiring diagrams, and test reports can be supplied with actuated packages — ask us what documentation is included with your order.

For parts: send valve markings or photos plus the failed component description to [email protected].
For actuation: send valve type and size, required torque (or we calculate it from your pressure and media), fail-safe requirements, voltage or air supply available, and control signal type.
