YS Controls, LLC

YS Controls, LLC, a for-profit limited liability company and subsidiary of Maul Manufacturing Inc., manufactures and supplies specialized valves and related components to U.S. defense agencies as a prime contractor. The vendor operates as a small business across its prime footprint (100% of recent awards) and competes in both set-aside and full-and-open procurements, though the majority of awards carry no set-aside designation.

YS Controls is headquartered in Santa Ana, California, where it maintains its manufacturing facility. The company's capability portfolio centers on industrial and fluid-power valve manufacturing — butterfly valves, linear direct valves, bleed air valves, and electrical solenoids — supporting military aviation, maritime, and defense logistics applications. Recent representative work includes a $23,280 firm fixed-price purchase order from the Defense Logistics Agency (DLA) Land and Maritime for butterfly valves awarded in December 2025, a $28,050 Total Small Business set-aside purchase order from DLA Land and Maritime for butterfly valves (October 2024), and a $67,515 purchase order from DLA Land and Maritime for electrical solenoids (May 2024). The vendor also holds multiple indefinite-delivery/indefinite-quantity contracts with DLA, including a $249,999.99 small-business-set-aside IDIQ focused on bleed air valves for DLA Aviation.

Customer concentration is heavily skewed to DLA. The top five customer agencies account for 92% of recent awards, dominated by DLA Land and Maritime (54 awards, $1.7 million combined potential value) and DLA Aviation (43 awards, $1.7 million), with the Department of the Army, broader Defense Logistics Agency, and the Department of the Navy trailing. The two rankings track closely — DLA Land and Maritime and DLA Aviation anchor both volume and dollar value, accounting for 71% of combined potential value across the portfolio.

YS Controls places task orders against five named DLA indefinite-delivery contracts: SPM4A711D5097 (7 task orders, $140 thousand combined potential value), SPM4A712D5021 (7 task orders, $150 thousand), SP047003D1393 (5 task orders, $401 thousand), SPE4A720D5181 (4 task orders, $133 thousand), and SPM76003D7004 (2 task orders). The vendor operates exclusively as a prime contractor (zero sub-award activity in the source data) and depends on its parent company, Maul Manufacturing Inc., as a major subcontractor for valve component manufacturing. Activity is sporadic — two awards in 2021 and 2022, one in 2023, seven in 2024, and one in 2025 — reflecting the episodic nature of DLA commodity procurement. Combined potential value across all 161 awards is $6.3 million, with $5.4 million obligated.
