Safety-critical testing. Reliable diagnostics. Proven performance.

In the world of industrial automation and process safety, reliability is everything. The Profiler™ SIS/Block/Solenoid testing system from SofTek Engineering provides comprehensive, data-driven analysis for safety instrumentation systems (SIS), block valves, solenoid valves, and on/off automation valves. Built to handle real-world operating conditions, Profiler delivers precise diagnostics that help ensure your plant operates safely, efficiently, and within compliance.

what it tests

Whether rotary or linear, the Profiler is equipped to test a wide variety of automated valve configurations, including:

SIS (Safety Instrumented System) Valves
Block Valves
On/Off Solenoid Valves
Rack & Pinion Pneumatic Actuators
Spring Return and Double Acting Valves
Automation Valves with Limit Switches

Key Features & Capabilities

Stroke Time Measurement
Profiler measures open and close times to verify valves meet required safety performance targets, crucial for emergency shutdowns or flare events.

Solenoid Current Draw Analysis
Evaluates the performance and response time of solenoid valves by monitoring coil current and coil actuation timing.

Air Pressure & Flow Measurement
Reads supply pressure and internal actuator pressure. Verifies flow coefficient (Cv) of regulators and solenoids which detects any restrictions in air delivery.

Torque & Friction Analysis
Calculates the force needed to actuate valves—detects sticking, galling, or buildup before failure occurs.

Limit Switch Verification
Checks if limit switches are correctly set at 0% and 100% travel. Improper settings can lead to false “open” or “closed” feedback to control systems.

Leak Detection (API 598 Standards)
Uses laser bubble counters to verify SIS and block valves are bubble-tight to the required industry standard—zero tolerance for leaks.

Commissioning & Post-Repair Validation
Profiler ensures newly installed or serviced valves are functioning correctly before plant startup, preventing costly damage from installation errors or shipping mishandling.

Why It Matters

SIS and block valves play a critical role in plant safety. If they fail to operate when needed, the consequences can be catastrophic. That’s why these valves are subject to mandatory periodic testing.

Profiler ensures:

Your valves open or close fast enough for emergency actions.
Air supply and actuator performance are within spec.
Valves meet leak-tightness standards.
Limit switches are giving accurate feedback to control systems.
Your safety system is ready to respond—no surprises, no downtime.

industry applications

Profiler SIS/Block/Solenoid testing is ideal for:

Refineries & Petrochemical Plants
Power Generation Facilities
Chemical Processing Units
Pulp & Paper Mills
Any facility using SIS, flare systems, or automated shutdown valves

data-driven decisions

With Profiler’s advanced diagnostics and visual reporting, maintenance teams can:

Prioritize valve repairs
Justify shutdown activities
Plan cost-effective turnarounds
Reduce unplanned downtime
Eliminate guesswork in safety compliance

Compliance & Testing Specs

Our SIS valve testing includes all critical data points required by most corporate and industry standards, including those based on API 598 and custom specifications. While we utilize a standard modeled after a leading global chemical company’s SIS protocol, we tailor testing to your unique needs and system requirements.

Prevent Failures Before They Happen

Every hour of unplanned downtime can cost millions. Profiler allows you to test valves in line when possible, reducing labor and avoiding emergency repairs.
