Tobul Accumulator

Safety Shutoff Valves

Tobul Safety Shutoff Valves (TSV30/50) are designed to protect hydraulic systems from excess pressure; shut off hydraulic flow and isolate accumulators from the hydraulic system; and bleed off/discharge system pressure from accumulators and associated equipment. The optional electrical solenoid cartridge valve allows for the automatic release/bleed off of accumulator/system fluid pressure in the case of an emergency shutdown or loss of electrical power.

The Tobul TSV30/50 consists of a main ball valve shutoff in an all steel body; a manually operated needle-type pressure bleed cartridge valve; and an automatic overpressure relief cartridge valve, with various models designed for use in 3000 PSI or 5000 PSI systems. Additional porting is provided for a drain to reservoir/tank, and an optional sensor/gauge.

With a straight-through, free flow manual ball valve of 1/2" to 2" diameter (SAE O-ring style), the Tobul TSV has the capability to meet industries’ diverse requirements for a durable, adaptable, cost-effective safety shutoff valve series for use with many types of accumulators and hydraulic systems.

Safety shutoff valve provides manual isolation of the accumulator from the hydraulic system
All valves have a straight-through, unrestricted full-flow opening
Each valve incorporates a safety lock-out feature to prevent unauthorized operation; this conforms to OSHA’s “Lock Out-Tag Out” program
Non adjustable factory pre-set pressure relief valve prevents over pressurization of isolated accumulator
Easy one hand operation
Optional Electric solenoid pressure relief valve can be ordered normally open or normally closed to meet system requirements
Machined from high grade steel with black oxide coating
