RS-2 Valve Exerciser
E.H. Wachs RS-2 Valve Exerciser (Portable Valve Operator): The Ultimate Handheld Valve Exerciser
Operating stubborn, stuck, or legacy industrial valves manually is one of the leading causes of back, shoulder, and wrist injuries among field operators. The E.H. Wachs RS-2 Valve Exerciser – Portable Valve Operator (Rising Stem-2) is the industry-standard handheld solution engineered to eliminate physical strain while significantly increasing operational speed.
As the trusted supplier of premium industrial machinery in Kuwait, Agrim Projects offers the E.H. Wachs RS-2 to municipal, petrochemical, and industrial facilities looking to modernize their maintenance protocols and improve workplace safety.
Key Highlights of the E.H. Wachs RS-2 Valve Exerciser
- Dual Compatibility: Specially engineered to accommodate both rising and non-rising stem valves.
- High-Torque Performance: Delivers up to 800 ft-lbs (1085 Nm) of torque to break loose stubborn, frozen, or heavily scaled valves without damaging the stem.
- Rapid Operation: Reaches speeds of up to 55 RPM, cutting down operation times from hours to minutes.
- Ergonomically Safe: Minimizes human fatigue and protects field crews from standard repetitive strain injuries.
Versatile Open-Hub Design for Rising Stems – RS-2 Valve Exerciser
The defining feature of the E.H. Wachs RS-2 is its generous 4-inch (101.6 mm) open-hub design. Standard valve operators must be mounted off-center or require complex setups to clear rising stems. The RS-2 allows the rising valve stem to pass directly through the middle of the tool’s drive hub.
This central alignment ensures that your operators can stay balanced and positioned securely directly over the valve during the entire opening or closing cycle. The RS-2 is capable of handling valves ranging from 6 inches to 60 inches (DN150 to DN1500), making it highly versatile for diverse pipeline architectures.
Uncompromised Power and Precision Control of RS-2 Valve Exerciser
For safety and infrastructure longevity, control is just as important as power. The RS-2 is equipped with advanced control features:
- Fingertip Variable Speed Control: Seamlessly speed up or slow down operation with an easy-to-use variable trigger, maintaining ultimate control over sensitive valves.
- Instant Forward & Reverse: Reverse rotation instantly to free stuck gates or clean out threads during exercising.
- LCD Revolution Counter: A built-in, highly visible digital screen displays real-time rotation counts, helping your crew keep flawless records and prevent over-torquing.
Available Drive Configurations of RS-2 Valve Exerciser
Depending on your site conditions, hazardous location safety protocols, and utility availability, the RS-2 can be ordered in two distinct power packages:
1. RS-2 Electric Drive (110V)
Best suited for facility operations, treatment plants, and service trucks equipped with on-board generator systems.
- Available with VITALS™ electronic torque control. This proprietary E.H. Wachs system records operating data and automatically halts rotation when preset torque limits are reached, protecting critical valve assets.
2. RS-2 Pneumatic (Air) Drive
The preferred option for wet environments, municipal excavations, and hazardous, spark-sensitive zones (Class I, Div 1 areas) such as refineries and natural gas pipelines. It operates reliably off standard portable diesel air compressors.
