Why choose Spence safety and relief valves?

Spence Engineering set and tests all valves in accordance with the applicable ASME code and API-527. Most competitive valves do not meet API-527, leading to premature simmering and leakage causing system problems and premature valve failure.

Spence Engineering Safety and Relief Valves are designed and manufactured with a more rugged body/bonnet design than most competitive valves.  This exceptionally rugged design withstands excessive piping strains that often lead to valve failure.
