Electric Gate Valve selection starts with the service duty
A Electric Gate Valve is evaluated for linear full-open or full-closed isolation. A gate moves across the flow path. Wedge or slab geometry, seat arrangement, bonnet construction, stem loading and body cavity design control sealing and operability.
Before quoting this configuration, close electric actuator torque/thrust, duty rating, power, controls and fail strategy and record all process, mechanical, operating and documentation assumptions.
Electric actuator torque/thrust, duty rating, power, controls and fail strategy. State power supply, control signal, duty cycle, travel time, enclosure, hazardous area, manual override and fail requirement.
Published information supports initial screening; final size, class, materials, trim, operation, tests and documents are fixed in approved order records.
Close the questions hidden behind the product description
Record the question, accepted answer and proof so the Electric Gate Valve proposal can be audited across disciplines.
| Review area | Engineering question | Required record |
|---|---|---|
| Gate construction | Wedge, parallel slide, slab or knife designs serve different pressure, temperature and solids duties. | Freeze the accepted value in the tag datasheet and verify it on the approved drawing. |
| Bonnet and stem | Bolted, welded or pressure-seal bonnets and rising or non-rising stems affect maintenance and thrust. | Name the controlling document, responsible reviewer and inspection or calculation record. |
| Bore and cavity | Minimum bore, pigging, equalization, vents and drains must be defined where applicable. | State the measurable requirement and connect it to a drawing, procedure or test result. |
| Operating duty | Gate valves normally require full-open/full-closed operation; throttling exposure needs a separate review. | Resolve the open point before release and retain tag-specific evidence in the final dossier. |
| Electric | State power supply, control signal, duty cycle, travel time, enclosure, hazardous area, manual override and fail requirement. | Resolve the open point before release and retain tag-specific evidence in the final dossier. |
Record exact standard designations and contract editions; resolve scope gaps and purchaser options before manufacture.
Service conditions that can change or reject the selection
Avoid prolonged throttling unless the selected construction is explicitly qualified for it; partial opening can damage gates and seats. The final decision must cover system interactions, end-of-life loads, degradation and how failure will be detected or contained.
Use order records—not generic certificates—for acceptance
Generic examples may explain capability but cannot close an order requirement unless they apply to the delivered valve. Use the valve standards guide to separate product, rating, dimensional, end-connection and test scope.
Design basis
Approved datasheet, drawing, bill of materials, rating basis and documented deviations.
Material identity
Tag-to-component material mapping with certificates, processing records and identity checks.
Inspection and tests
Inspection releases, controlled test methods, instrument identity, measurements and final acceptance.
Electric fail action may require stored energy or an external system; loss-of-power behavior must be explicit.
Do not infer certification or guaranteed performance from this page. Accept only the order-specific evidence required by the purchaser.
RFQ inputs that remove avoidable assumptions
Provide a controlled valve list or datasheet covering every operating case, interface, material, operation, standard, inspection, test and document requirement.
For a Electric Gate Valve, also highlight electric actuator torque/thrust, duty rating, power, controls and fail strategy. Identify missing inputs and provisional selections so they can be closed before purchase order release.
Send the service cases for engineering review
Send the valve list and project requirements. Raymon Valve will identify missing inputs, clarify construction and return an order-specific quotation basis.

Electric Gate Valve questions
What information is required to select a Electric Gate Valve?
Provide the medium and composition, all pressure and temperature cases, nominal size, flow or differential pressure where relevant, required function, end connections, materials, shutoff criterion, operation, standards, inspection and documentation. For this configuration, the review must specifically address electric actuator torque/thrust, duty rating, power, controls and fail strategy.
Which standards apply to a Electric Gate Valve?
The answer depends on the product construction, project jurisdiction and purchaser specification. A product standard may cover design scope while separate standards govern pressure-temperature rating, dimensions, ends, pressure testing, fire safety, emissions or materials. Electric fail action may require stored energy or an external system; loss-of-power behavior must be explicit.
How should Electric Gate Valve pressure and leakage testing be specified?
Define the test configuration and measurable acceptance rather than requesting a generic factory test. Include calibrated instruments, valve position, pressure direction and tag-linked results.
Can a Electric Gate Valve be supplied with an actuator?
Where automation is feasible, size from the worst-case valve torque or thrust curve, project margin, fail action, travel time, minimum utility, duty, controls, mounting and package test.
When should a Electric Gate Valve not be selected?
Do not select it when its qualified construction cannot satisfy the process, shutoff, materials, dynamics, maintenance or documentation requirements. Avoid prolonged throttling unless the selected construction is explicitly qualified for it; partial opening can damage gates and seats. The alternative should be chosen only after comparing the complete service duty.
