Question 1

What does this accessory do?

Accepted Answer

Hydraulic actuator drives a quarter-turn or linear-motion valve from a remote control panel — typical input is hydraulic control pressure (1.5-2× the line pressure for FC / FLS service). Double-acting design gives both open and close power; spring-return option available for fail-safe service.

Question 2

What valves does this fit?

Accepted Answer

Compatibility: Universal — fits API 6A 5M / 10M / 15M valve interfaces. The host valve OEM and model determine the exact mounting interface. Specify the host valve OEM, model, and serial number on the RFQ — Indus confirms the correct mounting kit and provides any required adapter sleeves.

Question 3

Is this accessory NACE-compliant for sour service?

Accepted Answer

Yes — body materials, fasteners, and any wetted parts meet NACE MR0175 / ISO 15156 hardness and chemistry limits. For full system NACE compliance, also confirm the host valve trim and any wetted control components.

Question 4

What signal / control connections are required?

Accepted Answer

Hydraulic supply line (typically 1/4" or 3/8" tube fitting per OEM spec). Optional: 4-20 mA position feedback signal, dome pressure transmitter, manual override on the bonnet. Specify the control panel manufacturer / model for matched fittings.

Question 5

What is the lead time?

Accepted Answer

Typical lead time 35 working days ex-works. Common configurations stocked at the OEM for quick dispatch. Custom mounting brackets and long-stem extensions typically add 14-21 days.

Question 6

Are commissioning instructions provided?

Accepted Answer

Yes — every accessory ships with the OEM commissioning instructions, mounting drawings, and (where applicable) wiring diagrams. Indus also provides on-site commissioning support in the GCC region on request.

Question 7

What environmental / hazardous-area certifications are available?

Accepted Answer

IP66 / NEMA 4X enclosure for outdoor service (standard). ATEX / IECEx Zone 1 / Zone 2 certified housings available on request for hazardous-area installations. Specify the area classification (Zone, Group, Temperature class) on the RFQ.

Question 8

Does this accessory affect the host valve's API monogram?

Accepted Answer

API 6A monogram requires that any added accessory be qualified to the host valve's testing protocol. For monogram-critical service, specify the accessory at the time of host-valve order and Indus arranges combined-assembly testing. Field-retrofit accessories are supplied as service items and do not affect the existing monogram unless re-tested.
