Project objective
Design a valve package for routine isolation, shutdown or depressurisation and coordinate mechanical dimensions with actuators, controls and testing requirements.
Offered technologies / Process plants
Automated shut-off and safety valves
We engineer and supply complete automated valve assemblies: valve body, actuator, controls, feedback and accessories. Pneumatic, electric and hydraulic options are selected for the medium, operating regime and required duty of each valve.
Operating context
The whole application matters.
An individual datasheet defines the medium, pressure and temperature conditions, materials, leakage requirements and specified failure position. Torque or thrust calculations account for the valve, operating cases and available control energy. The scope covers engineering, mechanical assembly, control connections, setting and agreed tests. On/off and safety assemblies address ESDV, SDV, XV or BDV duties; modulating applications integrate a positioner and the control system.
Engineering priorities
From operating need to design.
Supply interfaces
Process conditions, flange connections, face-to-face dimensions and actuator clearance.
Engineering output
Approved assembly datasheets, drawings, and material and instrument records.
Actuation and loss of control energy
Pneumatic assemblies can use spring-return or double-acting actuators; electric options are selected for operating duty and power supply, and hydraulic options for the required force or torque. The response to loss of air, power or signal is defined for the complete assembly. Manual emergency operation and stored-energy arrangements follow the operating requirements.
Accessories, controls and acceptance
Assemblies can include limit switches or proximity sensors, positioners, solenoid valves and air preparation. The application determines local controls, cabinets or panels, tubing and interfaces to PLC, HMI or SCADA systems. Acceptance verifies command response, feedback, travel time and failure conditions; partial stroke testing (PST) is included for suitable assemblies where specified.
Body construction and maintenance access
Ball valves can use split or welded bodies according to the application and maintenance requirements. Valve construction, mounting interface and required operating torque are assessed together with the actuator; a product family designation alone does not establish suitability for a particular safety function.
Supply boundaries
A scope you can specify.
- Floating- or trunnion-ball valves in suitable material configurations.
- Pneumatic actuators, air filtering and regulation, control valves and position indication.
- Control panels, tubing, air reservoirs or fire-protection covers according to the individual duty.
- Inspection and test plan, assembly drawings, functional testing and export packing.
- Quarter-turn and linear assemblies for ball valves, butterfly valves, gate valves and other valves according to their construction and duty.
- Electric and hydraulic actuator options, positioners and local or remote controls.
- Design and fabrication of brackets, adapters, control panels and cabinets for the individual assembly.
- Setting and checking travel ranges, signals and interlocks, FAT and on-site verification against an agreed test plan.
- Emergency shutdown (ESD) interfaces: final elements, shutdown logic and position feedback.
- Ball valve isolation assemblies with floating or trunnion mounted balls, split or welded bodies and corresponding actuator interfaces.
Before engineering
Inputs that matter.
- Which media, pressures, temperatures and flows must the valve handle?
- What fail position and opening or closing time are required?
- Which connections, space restrictions and control-energy supplies apply?
- Are partial stroke, air reservoirs, fire protection or special inspection arrangements required?
- On/off or modulating duty, operating frequency and required travel range.
- Available air pressure and quality, electrical supply or hydraulic power-source parameters.
- Signal and communication interfaces, local controls and area classification.
- Safety-function definitions and risk-assessment requirements.
Agreed with the proposal
Outputs and acceptance.
- Approved assembly datasheets, drawings, and material and instrument records.
- Records of specified pressure, leakage and functional tests; witness and FAT requirements are agreed before manufacture.
- Identified assemblies with accessories and packing lists organised by delivery stage.
- An identified complete assembly with settings, connection diagrams, agreed test results and maintenance information.
- Cause-and-effect matrix and agreed functional test records.
The actual scope and acceptance criteria depend on the application and contract.

Requirement
Design a valve package for routine isolation, shutdown or depressurisation and coordinate mechanical dimensions with actuators, controls and testing requirements.
Proposed solution
An individual datasheet defines the medium, pressure and temperature conditions, body and trim materials, leakage requirements and fail position. Actuators are selected using a torque assessment and the available air pressure. Solenoids, limit switches, control panels and accessories are then specified for the applicable ESDV, SDV, XV or BDV duty.
Proposed scope
- Floating- or trunnion-ball valves in suitable material configurations.
- Pneumatic actuators, air filtering and regulation, control valves and position indication.
- Control panels, tubing, air reservoirs or fire-protection covers according to the individual duty.
- Inspection and test plan, assembly drawings, functional testing and export packing.
The configuration example is a proposal for a new supply. It builds on historical experience with automated-valve stages for which completion and release of 111 assemblies are documented.

Before we start
Questions that shape the project.
Can a particular SIL be specified?
The requirement is established for a specific safety function. Design and verification address the relevant specialist scope, rather than selecting a valve alone.
